<HTML>Last summer I got rear ended at a traffic light, rear of my Z was almost ripped off.
I had a L28 bored out 40 and an E31 head.
The head sat in a guys garage for about 20 years. Dual webbers a header 2 1/2 exhaust.Car ran awesome. I gutted the wrecked car for parts, car was restored until the wreck. I took the engine out. Last night I took head off too install new cam, well this engine I did from scratch had block checked for cracks steam cleaned new engine kit, new everything, put about 15,000 miles on it. the piston tops are BLACK!! Should they be that black? How do I clean them up, the only place I see a shining surface is where the intake valve (was).
