Got the plane back together and ran it. Ran great compared to before. Then did the differential pressure test three of four exhaust valves were not seating properly. Clearance was correct. So we pulled the heads and all the valves. It’s gonna need a valve job. The were all pretty pitted. However cylinder 1 was 79/80.
so now I’m deciding what I want to do. Either get a new set of heads or have these fixed, maybe both...
either way firewall forward is much better, and my static rpm is a bit higher.
