biggest valve for stock fly cuts

[Thenemesis]

I have a set of completely built E7's that are ported and polished.. and somebody put in a bigger sized valve.. i had another set of heads that were stock and i compared them.. and the built ones had bigger valves. So anyway, how big of a valve will fit with the stock fly cut pistons? i still have to measure them, i bought them off a guy, and so i dont know there size yet. Anywho what do you know that will fit? i dont think there as a big as 2.02's tho

With a decent lift cam 2.02's can have some difficulty fitting with the stock pistons. !.90-1.94 at the most should fit a majority of the time without issues (still not an absolute guarantee though).

alright then.. if i do it then im just buying a 65mm tb to go with those heads and a matchin ported stocker intake.. should make decent power and not to much lol

I agree 1.94's x 1.54's are about as big as you want to go with......and that with a stock cam. Port that stock lower ( I may do a tech article with pictures soon on that) and throw on that 65mm tb it will make some good power if you dont have any piston to valve clearance problems!. Just get a little modeling clay, or play do (non stick kind) and bolt your heads down on your engine, and roll it over with a rachet/socket and then measure the clearance. shouldnt be to hard.
good luck
