Sooo.. I pick my head up from the shop yesterday...the guy tells me all of my guides are good and he replaced my bad exhaust valve. Then he says oh....for some reason I had to seat than new valve. So I go to slap it on last night and something doesnt look right. I throw a straight edge across all the valves and the one he replaced seems longer(or is just seated farther in the head) than the others. It is #3 ex that is new. The 1 pic is with me holding a straight edge(ok its a saw) on # 3 and 1...you can see the gap on 5 and 7. If I hold the edge so it touches 3 and seven...there is about a .020 gap under #1. I would pull the new and an old valve out and compare em to dbl check the shop....but I cant seem to get the cheapie spring compressor I got to do the job. Am I worried about nothing here....or should I be concerned?
