GM 317 Heads that i bought from another LS1tech member last year, heads went 9.0 @ 158 with my 370, GT55, truck manifold setup. Prior owner went mid 8s @ 160+ in a 408 mustang. These heads flow like crazy and I really hate to sell them, but i am going a different route. Here are the specs of the heads:

-Castings were bought new and have around 2500 street miles on them
-Intake and Exhaust runners have both been fully hand ported
-Chamber work
-Deshrouded valves
-3 angle valve job
-shortside radius work on the intake
-Patriot dual gold extreme valve springs that are good to .660 lift
-All above work was performed by Opel Automotive Engineering

Ive recently had these checked out at my machine shop were they have just installed new valve guides, and resurfaced. Chambers are around 68cc. Head come fully assembled with rockers. Also the heads have been drilled out to accept 1/2" ARP head studs.

Price is firm, 800 shipped.
