[Fot] TR4 exhaust valve question

[David Gott]

Amici,
I recently had a (catastrophic) failure in my engine that involved valve and piston interference.  I’m using the gas flowed high performance stock size exhaust valves that Moss Europe sells.  Have any of you had any experience with these valves, good or bad?  Trying to rule out a bad part versus something else.   The “penny” broke off the “stick” but I’m not sure if that caused the issue, or an issue caused that.   The stem was not bent… but is now just a stem!  Flows just a little too well now!
Any experiences with those valves?  (HRG rules require stock size valves)
Thanks,Dave Gott
