Head choice

[Gladiator2004ad]

I've recently decided to take on a 351W stroker build. Its going 408 and will be EFI.

I've found a couple of deals on heads and would like some input from those who have ran, or have had experiance with others who have ran these heads.

I've found a set of World Products Windsor Sr heads. These are iron, 200 CFM runner and 2.02 intake 1.6 exhaust valves. Around 600 bucks.

Also found a set of Edelbrock Performer RPMs. These are of course aluminum, 170 CFM runner and either 2.02/1.6 or 1.9/1.6 the guy doesnt know, and i havnt seen them yet, for 500 bucks, with a set of 1.6 roller rockers.

I know the Edelbrocks are a great deal, but they arent quite as big as the Sr heads. This is going the be a street car/weekend warrior kind of thing, so I'm thinking the irons may be more reliable and hold up better to the stress of daily driving. So my question is, is the trade off of weight worth the 30 CFM?

dont go with iron heads. there is nuttin wrong runnin aluminum heads on a DD. even as big as a 408 stroker moter. and they save some weight. but thats just my .02

I'm sure Greg from XSR or Trai (nastynotch) will chime in when he see's this, but if not pm him and ask him about these heads. He should know and he will help ya out

Victor Jr's..ported right

[Gladiator2004ad]

Well I've been doing a bit more research on the flow numbers, and for the most part they are virtually identical, with the Sr's outflowing the RPMs at .400 - .600 lift, but by a very miniscule amount.

It seems to me that I'd be better off saving 100 bucks and, what? about 40 lbs off the front of the car, with the RPMs.

[XSR]

Go with the Eddy's, they are a good foundation. They will last as long as the irons, as long as the motor is tuned. The Perf.s will perform nice as is, and even better ported. So you can always grow with them, or even resale them.

[Gladiator2004ad]

thanks guys, just jewed him down to 450 on the RPMs, this 408 is one step closer to completion.

[XSR]

You best jump on that deal, as long as they are in good shape. You can always resale them in the future, and not loose a dime.

[Notch93]

dont go with iron heads.

Why not use an iron head? Little before your time, but ever hear of the TFS Street Heat heads.:yes1::lol1::lol1::patriot:

+1 you better get them for that price.later on i would step-up to a set of XSR ported high ports.:thumbsup1:

[RoadconeTuning]

no point in running an iron head anymore... you can get aluminum heads for just as cheap and they are lighter and everything is better... there should be no difference in durability... they'll both wear out valvesprings and guides just as fast...

These were also in Alum. Thats what we run

[Notch93]

True, they re-made them in aluminum. But back in the late 80's when they first came out, only the irons were available.

[XSR]

There is nothing wrong with iron heads, or aluminum. There are a few dislikes with iron heads... 1. the weight of putting them on, and taking them off. 2. if you ever have them ported, your porter will most likely not like you to much. LOL! joke!!! You don't see many high flowing iron heads either. I know I did a set for someone about a year ago, and they turned out nice. They were the World Sr's 200cc's, and made near 500rwhp on a street 408.

[bonesgt]

Greg, ya trying to say you don't like me no more??? hehehe:taunt:

$450 for Alum heads and rockers is a good deal, jump on them!!:thumbsup1:

[SVTSkip]

I'd go for the $450 deal even though I'd like to see something a little bigger on that application. I run 185cc 2.02/1.6 aluminums on my stock bore stroke 302 though, so my objectivity is likely skewed some LOL ! I have access to those heads for $800 a set new plus shipping though, so my decision was made for me. No probs on aluminum on a DD either. I've been enjoying them for years. Enjoy the new power !

[nitrostangracin]

Something important to find out with the Edelbrock deal is specific valve size. A big cube Engine and a 1.90 valve will not get you a full benefit of the head.

[WILDSTANGRACING]

just get your cfm flow right for that strocker so you can enjoy that power from your package iron or aluminum that thig will rock good luck man

There were in Alum when they first came out. The set that we have was bought in 1990. They stoped making them for a while, then brought the Alum. back out as a non-emission head.

A little update on this subject. He bought the heads, bought the valves (2.02) and they don't fit, they are rather large.... So... He bought a set of 1.90 valves and we are going to slap them on his 95GT. We might put the 408 on hold. He told me if I can get 300 to the wheels with a stock cam and just these set of heads he will put the 408 in either a coupe or his 1973 Mach 1. I am pretty sure with Eddy heads, stock cam, 1.7 rocker, Eddy upper/lower, 75mm TB/eblow, CAI and 24#ers we can hit 300 on a stock PCM. If not out comes the TwEECer and I'll burn a chip for a couple $$$.

[XSR]

I would'nt get my hopes up alot on the 300rwhp#. Not with the stk cam, and what about a intake, tbody, maf, etc....

[Stable]

^ I'm with XSR on this one....300 to the tires on a stock cam?

[Silver91Hatch]

Well its pushing 228 right now before the injecotrs, maf and TB

[nastynotchback1]

I was going to say that but didn't.Hey how about answering your phone.Why ain't you working???

[SVTSkip]

You could maybe get to 300rwhp on the stock cam, but the question would be why ?

[XSR]

I would expect around 275-280rwhp after heads, tbody, maf, and injectors.

nastynotch..... I took a personal day today, and yes I've been meaning to call you!!

[Silver91Hatch]

Well I seen on Corral that someone has a stock bottom ended explorer motor in a mustang with GT40P's, 1.7RR, long tubes, TB, upper/lower intake, injectors, maf and a CAI making 301 to the rear wheels on a stock HO cam.

Here it is...

[fast50]

My brother in law made 285 on a mustang dynometer with only 10deg timing. On a dynojet it would have been 300 easy. We could have turned the timing up and probably got to 300 but we were getting ready to spray it so we had the timing turned down. GT40P heads are amazing.

[WILDSTANGRACING]

good luck

dont belive all of the bs about Dynojets making more power...it depends on if the MD is using SAE numbers or not...and it depends on the DJ

[nastynotchback1]

So are you willing to put the dyno time/money into it and spend all the money to test with it until you hit your goal?your not gonna just slap the motor in and bam 300 rwhp unless for some reason you hit it dead on.

[XSR]

If you spend alot of time tuning it, yeah maybe. But, for the most out there, just bolting heads on, will not make that power. We had a stk bottomend 302, with ported E7's, Ecam, intake, all bolt ons make 285rwhp, about 8yrs ago. So, I'm not stating it can't be done, just that you have to spend alot of time tuning it. Why no cam? Nothing is sweeter than hearing a nice lopeing Mustang at a readlight......

[Silver91Hatch]

Well the funds are tight and we have the heads now. He is talking about waiting and slapping a cutsom grind cam in it in about a month.

[SVTSkip]

I'd wait for that cam ! :yes1:

[XSR]

That makes sense, and let me know if he does go the custom route. As, I am a dealer for comp, and can custom grind whatever he wants. I do my own designs, and I don't let comp pick them for me. They do have alot of knowledge, but I use alot of personnal expierence.

[Silver91Hatch]

I will for sure. I was going to get one from you for my coupe but I found a cam I couldn't turn down, FREE. I was just going to use it for mock-up but didn't have the money before MW so it's done now.

[XSR]

Not a problem, just let me know if there is anything else I can help with.
