I have a rocket block that I got from a guy thats bored over 30. My 4.1 V6 died today..... So Im starting from scratch... I need V8 motor mounts, radiator, fan shroud for V8, clutch fan....etc... I want to go with Aluminum Cylinder Heads and a hydraulic roller cam... Does anyone know who makes the best aluminum heads? And what kind of pistons are best for high compression?
