2.02/1.6 PTV

[tc_white]

hey fellas i just bought a set of edelbrock performer rpm heads with 2.02/1.6 valves. im wondering if they will bolt on a stock 5.0 HO bottom end. if so how much lift is possible. can you run big valves with stock cam, etc...?

any input appreciated.

most of the time they will not work with out notching the piston.... but it really depends on the cam your running check to be sure they will or will not work i normaly just bolt the head down with no gasket when i do this just so there is less room to start with.:thumbsup1:, as far as i know the tfs twisted wedge head is the only 202 head that will work on a stock piston.

It should clear with the stock cam, even with 1.7's. We use to run TFS High Ports with the stock cam with 1.7's back in the early 90's, and had plenty of room.

But the only way to be positive is to Clay it, to make sure you have the PTV clearance. No two motors are the same.

i think all the tfs heads work with stock short blocks bc the way the valves are, i think its only the edelbrock ,afr,and heads that are all direct inline valve heads that the edge of the 202 valve hits on the edge of the valve pocket on the stock pistons. but just like eric said ALWAYS CHECK PVC!

I'm fully aware of the Twisted Wedge's, those are the only TFS heads that have the rotated valves that are moved over the center of the cylinder bores.

A TFS High Port is an inline valve head, just like the Edelbrock Performer RPM heads he bought.:yes1:

ok thanks alot fellas. i didnt know if i just stuck with small lift, would they would work or not without having to pull the motor and notch the pistons. i was really hoping to throw a small cam in it with those heads and run it. lol oh well.

[tc_white]

one more thing...i know edelbrock makes two performer heads. the rpm head and the regular performer. what are the main differences? just valve size or are there different flow charts for the two?

The RPM head does not have the provisions in the back of the heads, if you wanted to keep the smog stuff. Plus the RPM heads are stud mount, instead of pedestal, thats the only differences.

You can notch the pistons, with the motor still in the car.:yes1:

kk.. i dont mess with the tfs heads alot, i figured that was one of there trade mark things with the rotated chambers. learn somthing new every day .

They don't have canted valves ;)

Just the chambers are rotated on the twisted wedge versions. The hi ports are normal 20 degree inline valve windsor heads.

haha i see this after i edit my post thats funny lol.. but yes that is what i ment, i dont understand why they dont follow that design with all there heads if it seem's to work.

[NC STANG GUY]

No problem man,lol. Hi Ports were out a long time before they tw heads though and they kick ***. Especially the original ones.

this is true very true.. if i didnt already have ported canfeilds i would have the old highports on my new motor

[NC STANG GUY]

Yeah those are nice too. Use to have a set of Bennet ported Canfields on my old 357ci engine.

I had a set of the Wil Burt Trick Flow High Ports with 1.94/1.60 valves fully ported on a 306, back in 1991. All I can say, is that coupe moved out.:yes1: Still pissed it was stolen from my driveway with a flat tire.:angry: :cussing: :angry: :cussing:

wow..... talk about wanting somthing bad even took it with a flat tire. wtf:bat:

Thieves suck. That's the bad thing about foxes,they usually are in pieces hours after being stolen. They need a good :bat::bat::bat::bat::bat::bat::bat::bat::bat::bat: :bat::bat::bat::bat:

Definitely clay them to make sure. I just put on a set of 2.02 /1.60 heads and have no PTV issues with a Stage 1 Trick Flow cam and pistons with no valve reliefs. There are so many variables to account for so it is best to clay them to see what you've got to work with.

The bad thing though, I'm 90% sure it was a friend. If I ever find out the other 10% is correct. I still know where he lives, and he would go for a boat ride in the Atlantic, and might not come back. Some things you can never forgive.:nonono1:

well on that note you were at my house when that happens lol :yes1: :thumbsup1:

[GEO302]

I have a set of Twisted Wedge heads with 2.02 / 1.60 Size valves
I have .544 Lift cam
My set up clears the stock pistons on my stock short block.

ok thanks. if you can elaborate a little more on the piston notching with motor still in car. is there a tool for that or just a steady hand? lol. iv heard of people doing that but was always afraid to.

isky makes the tool. you have to pull all the valve's out of your heads to do this though. :thumbsup1:
