I just bought a pair of the Spotlite Kustoms aluminum valve covers (the ones that look like the OEM steel covers but with fins).

Didn't take long to realize the stud holes are too small for the OEM grommets. The lower portion of the grommet that sits inside the stud hole is about .100" larger than the hole. Figured I could just shave that part off and try it, but even after that the remaining portion of the grommet is still too fat to seat correctly in the recessed area around the stud hole.

Wondering if anyone else has run into this, and what you did to make it work.
