[QUOTE="vibrac, post: 43649, member: 60"] I do hope you don't mean rotational grinding full rotation I was always told that way lies deep tram lines in the alloy for the same reason that you grind valves 1/4 to third rotation lift and replace further on on the other hand if you are talking fine skimming with an appropriate lathe tool then if you can set it up accurately its certainly another way. I always find keeping grinding medium off the liner spigot sides the hardest I do dob a bit of grease close in but I dont think it does a lot but the last thing you want is to do is increase the recess diameter in the head [/QUOTE]
