So I measured and remeasured the valve stems as well as the boss guides for cylinder #2.


Intake valve stem: 0.3415"

Intake boss guide: 0.560"


Exhaust valve stem: 0.3415"

Exhaust boss guide: 0.559"




I measured the ID in the Felpros using a caliper, but they seemed a little smaller than the ones removed. I wanted to stop by a Chevy dealership's parts department to see what they've got, but they were all closed today. However, I did find these viton seals on eBay:

- Metal Clad Viton Valve Stem Seals 11/32" x .562" sb Chevy Ford Chrysler sbc | eBay

- VITON VALVE SEALS 11/32 SBC SBF GT40P PONTIAC .520-.565 | eBay
