Picked these up in 2008 planning to install them on my '87 T/A. They have some light intake port work and new Comp springs, locks and retainers. Springs are good for .525 lift. Casting # 10088113, 1.94/1.50 valves
I cleaned them up and they have been sitting on my tool box ever since. They include stock valve covers and rocker arms. Only thing they need is to be blown off and installed.
