The heads are off of a 1986 Pontiac Trans Am carbureted 305. I had the heads machined they surfaced them put new valves in (2.02" intake and 1.6" exhaust). The guides were redone, they have screw in studs, and the seats have been done. New Comp Cams Valve springs and retainers that support up to .650" lift on flat tappet camshaft. The machine shop did a full port and polish they matched the exhaust ports and also blended the bowls. These are 58 cc heads and I selling them because the motor I built I used a set of domed pistons and the valves are hitting the piston tops so I need something with a larger combustion chamber. These would make a nice set for a 350 with flat top or dished pistons. These heads have not been run since being redone I will post pictures upon request. Thank you for taking the time to read my ad I will try to answer any other questions you might have.

Thanks again,

Jeremy Russow
