[QUOTE="nkt267, post: 51175, member: 245"] Do the larger valve heads still pass the top of the liner? I have seen a pair of barrels recently that had the inlet side of the top of the liner ground away, almost like the valves would have clipped the liner otherwise. I was asked to check the bore size as the owner wanted to fit low expansion pistons in place of the Specialoid ones he had.. I've never seen this, has anyone??..John [/QUOTE]
