A pair of early Rover heads that were machine shop refurbished in 1973, but never installed. Came with a Buick engine but they are 4 stud heads. Decked, valves and seats ground, still has prussian blue around the seats. 7 of the intake valves are marked GM. The rocker assembly is missing. I dismantled, inspected and cleaned, look AOK. $200 per head OBO, located Grand Junction, CO. Sorry, you'll have to ask for pics.
The short block engine is available, as removed from a car. Cam and lifters trashed but crank looks good. This is an oddity, a Buick high-compression engine code but has 6 studs per cylinder like the Olds version, instead of the 5 found on Buicks.
