Hi all... does anyone have any experience porting 351C heads that could describe the "proper" short-side shape? finally able to pull the heads off my BOSS302 to replace the head gaskets, and decided to have them flow-tested. well... everything is fine till .600lift, where they explode in turbulence :evil: spoke to Jay last night, and he feels strongly that when this gets fixed, the motor should pick up 100hp. HELLP!! thanks, Duke.
