[QUOTE="_JOE_, post: 1286501, member: 77507"] I had to go .003" and .002" smaller shims on the intakes. The exhaust valves were in spec but at the bottom so I bumped them up to the top so I wouldn't have to mess with them again. I thought sure they would stay in spec till the second piston swap. The plan is to go KW s/s once I have to shim again, but I was hoping to finish this season before that happens. I will be riding more this year, maybe 80 hours or so. My local service guy says he will cut the seats for 110 bucks using a manual cutter. Is this sufficient, or should they be done on some sort of mill or something? I can r&r the valves and stuff myself. I just have this fear of it costing $1k+ to fix the head up before I hit the 100hr mark. :bang: If that's the case this is the last performance 4t that will find it's way into my garage. :| [/QUOTE]
