Oh boy. Valvetrain geometry issues.
Thanks. I had read about the EQ guide clearance issues and not know the history I took the heads to my machinist and he gave the thumbs up. With my reground cam and . 028 head gasket I checked and it looks like the factory pushrods are pretty close for the taller valves so many just get custom for the shortest valves. I am using a checking pushrod to verify.
