Odd valve stem seals needed?
11/32" stems and .56X guide diameter...
All I can find are sealed Power ST-2001
I'm trying to avoid doing any additional work like cutting the seats down .530 because as soon as its running and moving it's getting the engine replaced.
Any other options out there?

Well the simple fix if u have stock dia vlv springs is the little O-ring seals that install in the groove high on the stem but below the "keepers" groove. Use a slip on protector to move the O-rings over the keepers grooves. U need to use the "splash shield" vlv retainers for these to keep the splash oil off the stem on the intake vlvs. They kinda big ugly retainers on top the vlv springs. But thats the easiest fix w/o cutting guide bosses. Im thinking there maybe PC vlv seals that dont need machining but dont have any part numbers for u.
Hope this helps.
Now im not sure if these O-rings and splash guards are for the 11/32 vlv stem. I recall 5/16" vlv stems. Sorry for confusion but u need to research before use.
