I have a professionally rebuilt B18C1 head with unpainted valve cover, 1999 GSR camshafts w/ gears, caps, Supertech valves, dual springs, titanium retainers, steel keepers, and Skunk2 lma. Head has 0 miles on it since rebuild. I'm asking $550 shipped OBO. I Need to sell this asap to complete other projects. If you need more info or pics call anytime at 606-416-2639. Thank you for looking!
