I’m re-building my cylinder head and have lapped the valves. I’ve read suggestions that when the head bolts/cam retainers are torqued into the block the tappet gap will reduce 2 thou versus measuring them on the bench. (Bryan N I believe suggested this).
How accurate is this? I have to get some new shims at $5 ea. & I also don’t want a several thou surprise that makes me remove the cams again.
