Hello Everyone


so I'm having an issue where my Exhaust valve seals keep "popping off" and creates blue smoke through the back, this isn't the first time this has happened & its not in one particular valve either, its only on the exhaust side valves. Motor is still new less than 7k miles, Motor was built by F-P-S by Troy, I talked with Troy but he said he never had an issue with his seal popping off so he sent me an extra set for good measure, so hopefully I can install them this weekend.


is there any reason as to why these things keep slipping off? I know positive valve seals are not ment to move. The heads I'm currently running are Avenger Heads which F-P-S use's in their engine builds.

I believe they used to be canfields recasted as avenger which are built in house by FPS. I also attached pics of the built motor, but no specs on heads. (Sorry for the bad quality) motor is a 351w stroked to a 392w

is there any tips you guys recommend? or should I just pull head outs toss it and purchase a new set of heads?
