I have a set of bare heads and Intake from a 2007 GM 604 crate motor that blew up on me. The heads have a few spots where they are dimpled but nothing terrible and the have been pressure checked and are good. I also have the push tubes, rocker arms, and lock nuts all in a box. The only things the heads have on them right now are the rocker arm studs. $600 for everything. I have pics i can text or email to you. Located in Omaha NE. 402-707-2745
