Lets have some fun!

Before you buy any heads, I'd pull your old ones and look at your pistons. If you have a flat top with valve releifs your OK, but if you have a factory style or TRW 2316 that stick out of the deck, they can only be used with factory open chamber type heads!

So if I pull the heads and they have the factory type that stick out of the deck they would have to be changed out before I was able to put on new heads? Would I need a new Carb with the setup you recommended? Right now i'm running a 670cfm.
