• I say again don't buy their intake valves.
  
  Reason I say this, is because they stated on the RockAuto.com website their stem diameter is 7.925mm
  
  I called Sealed Power to confirm this and they said that it is correct.
  
  Bentley states new intake valve stem diameter of 7.970mm.
  Bentley also states wear limit on said valves of 7.920mm.
  
  .05mm is the equivalent to .002" rounded up (.0017")

• John at air cooled engines plus will sell you all stainless valves for probably what you have in the rockauto ones.

• Dang, I think I had 8 per valve intake and ex. If you still need them. I had around 60.00 in all 8v. The OEM sodium filled ex valve is almost that.

• Does Air Cooled Engines Plus supply oversize stainless AAZ valves as well? Does anyone know what kind of stainless material they use?
