Valve job on os valves

Dont know how i missed that my apologies Only 16 and my eyes are playing tricks on me:eek:
No Problem, there are times I wish I was 16 again,
Another way that OS valves can help is, if you have new seats cut into an existing valve seat, that can sink the valve further into the head and that really hurts flow at low lifts.
Cutting in new OS seats gets you a new valve seat up on top of the head where it belongs.
