Unfortunately, if I want to keep my air grabber, I'm stuck with the Edlebrock Performer 440. Its an inch higher at the back than stock and I had to put a thinner air filter on to get the air cleaner lid to clear the air grabber box.

From what I've read so far on this board, it would seem that these aluminum heads are the way to go. Is that something you can buy and bolt on without knowing what pistons/compression you have? Not that I would dream of doing the work myself but if I see a good deal, maybe I can jump on them. Or maybe my intake is "not much better than stock" then they wouldn't flow so there'd be no point.
