Just to be careful I went over to my machinist and we pulled some of the head apart to look and see if it needed any work.
One of the thing we noticed was that the damper spring was digging into the aluminum a little bit where the valve guide comes through and also was offsetting the spring retainer to one side in one instance which was putting the retainer quite close to the cam towers.
I got on the tech support chat with Comp and told them I was running a stock cam and only turning 6k with my 2.5 and that the dampers were digging into stuff and that its OHC with not a heavy valvetrain and they said I would be fine not running the damper.
I was concerned that the spring may have a goofy harmonic at a lower RPM but they said Id be fine.
So ill be getting a valve touch up, some positive type valve seal on the exhaust valves and mopar valve seals on the intake, comp 942 springs and no damper.
even though the head was ingesting oil, and there was a little goofiness with the spring damper, the valvetrain with the PT lifters was dead quiet.
