I should have listened to the other reviews. These seals fit an 11/32 valve stem great, but I can push them right on and pull them right off of the valve guide itself which isn't correct for a positive seal. I should have to tap them on with an install tool and not be able to pull them right back off with two fingers. Pretty upset with them.

Bought these because they were supposed to be for a big block Chevy but they weren’t even close to fitting.
