Porting question

I don't know what a stock max wedge port size is but you are right next to
my Indy 440-1 port size @ 1 5/16 x 2 5/8.
Someone put some effort into those heads.
Looks like you can open up your intake some if your not using the same one that came
with the heads.
I like to see a iron head 440 that can whoop on a cubic dollar aluminum head engine.
I think you got a lot of cylinder head for your money. Hope they do you good.
I know an older mopar engine builder/racer who has been racing hemis and maxies since the sixty's who has a set of 906 iron heads he opened up to put a factory cross ram on. His cars are very strong and hook up great. He was porting heads long before the aluminum heads were available.
He told me you have to be selective due to core shift as not all of them can be used.
