Review on πŸ› οΈ COMP Cams 503-16 PTFE Valve Seals for .530" Guide Size, 11/32" Valve Stem - Set of 16 by Jason Franco

Revainrating 5 out of 5

The seals appear to be working well; Haven't run the engine yet

THEY MAY NOT WORK ON YOUR HEAD IF YOU DON'T HAVE THE VALVE GUIDES FINISHED. The seals appear to be working well; I haven't started the engine yet. Using the plastic grommet that comes with the seals to install them makes them easy to install without having to take them apart.

Pros
  • Valve cover and stem
Cons
  • not sure
