Smallblock Heads?

Well...those BA heads are not much better than edelbrock heads unless you order them with pushrod holes deleted and redrill the intake flange for w2 pattern then drill the pushrod holes where you want them.
I've done a set this way and they ended up flowing 325cfm @ .700 and 308cfm @.500 on my bench which is outstanding. But they are not cheap.
For the money Indy's -1 head with hand porting is the best deal.
You can use their rockers for a budget build or TD for more rpm/bigger cam.
And you don't have to cut your headers up like you do with the BA heads.
Just a thought....
