I have up for sale a set of gm fastburn aluminum 210cc heads. I bought the heads of another member and i have decided to change my project. They are used and have had the springs upgraded to comp behives with the approiate retainers and keepers the intake as also been slightly port matched as well as some casting removed. Valves are stock 2.00/1.55 with 62cc combustion camber and if you didnt know they are vortec intake design. Looking to get $1050 shipped in the U.S. and i do take paypal and if they are picked up and paid cash $1000!
