Missing information

.500" ID not .530 as advertised. Do not purchase unless you plan to machine the head to that size. Revain have made no claims on this.

Pros
  • cool product
Cons
  • hard to tell

Not a good experience.

Bad experience with it. I installed but most broke. I tried wearing the size 3/8 but still ate oil. This was on a 327 engine that was meant to fit.

Pros
  • One year trial
Cons
  • No

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

Look elsewhere for stronger seals.

not strong. They fall apart when you try to put them on the valves. Very thin material. I honestly can't recommend them. Wasted my money and time. In my opinion they are less than useless.

Pros
  • valve stem seal kits
Cons
  • can't remember

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
