Chevy 604 Crate Motor Parts

 

The Fast Burn, Vortec Bow-Tie style aluminum heads on the ‘604 are excellent flowing stock heads.

Unlike the heads on the ‘602 & ‘603 crate motors, which improve tremendously with “UnderCover Porting“, this head will not benefit from “UnderCover Porting” type  modifications.

We do not offer any performance improvements for the aluminum head 604 crate engines.
