intake selection for 600hp 451 ci

Bobby, I didn't see anything wrong with his heads or there description.
Everything looks good but actual performance.... IDK. It looks like high 500's for HP.
I was under the impression that the Cometic gaskets needed a certain finish to be used or is that a certain Cometic gasket that needs a certain finish.

The Victor should be worth a few more HP. I don't know if it is worth the price vs. gain over the Torquer unless "That" number (HP) is really "That" important. I'd love my future W5 stroker to make 600, but running the time is more important to me than a big dyno number.

I would not swap head gaskets for a .05 gain. It is not worth it. IMO, just dyno it as is. Before you bring it to the dyno, ask the guys that are there.
