ok... so youve already taken the heads off to cut the pistons... but threw e7's back on???

as far asi know the stock flycut **** wont be enough...

i just think its hilarious that your basing your head choice compleetly on intake valve size

but hey, wtf do i know right?

 

Victor jrs would be way too much cylinder head on a 306.

 

Only my old version is up, but here's the new sticky version. Hope this helps.

wow lots of info!


You will notice a differnce, they flow alot better than the stock heads

I have thumper ported gt40p's and it droped 2 seconds off my horrible 1/4 mile time with a tfs1 cam

 

combustion* cumbustion just looks like something that belongs from a **** title

 

the pistons are fly cut but the e7 heads arent on, im looking for ehads to put on it. i will be building a 347 stroker in about 2 months

 

then put a real head on it if your going to be building a stroker

 

hey buddy i have a set off gt40p heads, and what do you do to make the 1.95(i)-1.54(e) fit on those heads , these heads are stock never seen a machine shop what do i do thanks. i think thats better than 1.84(i)-1.45(e).
