heads.....
OKAY.... My mustang has a 331 stroker bottom end... Stock heads.. X303 cam... GT40 intake... SRP flat top pistons...
MY QUESTION IS:
If I buy GT40P heads, and port them and match them to the GT40 intake, is it gaurnteed to fit? (why wouldnt it? arent they a little bigger in every way than the stock heads?)
It would yield SOME horsepower right? I am low on money and want to do this temporarly.

if you put gt40s on a 331 i will come to your house and stab you. they are horrible heads. i wouldnt put gt40s on a stock motor if you paid me.
get some afr or tf heads in the 185-190cc range. while your at it, get a new intake manifold. let me guess your using the stock tb and maf too?
