Valve Stem Seal - 05/23/11 01:58 AM

I bought a new set of Valve stem seal for 906 head. In the box, there are 2 different type of Valve stem seal, 1 is soft and short + 1 is hard and longer. Nothing look like an old one I removed, which is same for both exhaust and intake.

Those Seal I bought look like the picture below. My question is hich one for Intake, which one for Exhaust?

Yes correct, the short seal is the OEM style for the exhaust.
The black Nylon plastic seal is OEM for a Small Block Chevy.

Do yourself a favor and put the positive style OEM seals on the intake side at least
