Hi guys, Im currently rebuilding my head, just had new guides and seals pressed in, and now im going about lapping the new valves in. My question is, should the new valves sit this high up in the seats? or would it have to be regrinded? also, two valves in particular, an inlet and an exhaust, are really hard to push in, and need real force to pull out, any ideas on what i can do for this? Cheers guys
