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

Revainrating 5 out of 5

They fit me perfectly

The top and bottom springs on these seals provide a secure fit on the head. Others have previously removed the head and moved with the valve stem. They have worked great for me.

Pros
  • Spare parts
Cons
  • Some little things
