Headgasket considerations
I've been building a H22A7 (Acord Type R) engine for my friend. The head was reconditioned in a reputable local shop. I got it back assembled with new valve seals, stiffer springs and titanium retainers which I had supplied eariler. They had to deck it, refresh vavle seats and clean valves. Usual job. I had ca. 6 heads made there and no problems at all.
But problem started with this head as I wanted to set a valve lash. On ca. 10 valves I can't even stick the thinnest feeler gauge. WTF?!
I even changed setting screws to those coming from F20 engine (additional 0.85mm comparing to H22 ones). Still no go. I assume the head has its valve seats ****ed up as valve stems don't seem to lenghten in time, do they?
So i'm going to make a warranty claim on their job but besides of the result of the claim, the question is if I can reuse the headgasket? It's OEM one. The engine is still out of car, no oil inside etc. Completely fresh.
Cheers

Re: Headgasket considerations
C'mon it's not the first time... Anyway I had this engine revised by my friend who has 15+ years experience in Hondas... His opinion is the same like mine.
