Many old flatheads used the same valves for intake and exhaust, did not realize this when ordering, and failed to notice they where 30 degrees ( my fault). The oversized valves require much more care to get valves properly seated. Would have bought a set of OEM type valves in hindsight. Returned and ordered 8 of the exhaust valves.
