Hey everyone,

Currently having issues with my 392w stroker built by FPS.

for quite some time I noticed my exhaust will create smoke during idle, once the motor has reached operating temp. I Checked compression and everything looked good. I took off the Valve Covers and noticed my exhaust positive valve seals popped off.

i had this issue before and had the shop who originally installed the motor re-seat the valve seals but again I'm having this issue.

what could cause this? incorrect seal size? overheating? Should I go Viton Seals?

the Cylinder heads are FPS "Avenger" heads.

I would work on this myself but have no time, anyone recommend a shop locally in bay area maybe south bay?

thanks for the help everyone!
