Aftermarket cylinder head debate - who's the best

MObarracuda said

I am building the 340 to achieve a very modest 350-375hp, flat tourque cammed engine for my A904, 8 3/4 - 323 geared rear end '67 Barracuda fastback. I am still selecting components for the build but I feel the cylinders head selection is too important to just guess and hope I made the right decision on product and supplier.

As others have mentioned. That figure is easily achievable with stock heads (even the small valve) without any work. I've got J heads on my 340. With nothing more than some cleanup work, work on the turn and a good valve job. And I make about 420 horse. There's a local headshop/raceshop that can do all out porting, cleanup, valve work, etc. For about 1000. That should get me in the 260+ CFM flow area. Good enough for 550 (potentially more) horsepower. If I want it in the future.

As nice as edelbrock or indy or whoever elses heads are. If you wanna hit your budget and power. I would look at stock style heads.
