When installed the kit yeilds a 124 engine with a compression ratio of 11:1. 960 taller than stock, there are no frame clearance problems, and a stock EFI Throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold.No fuel or ignition system is included.
