I would go with the felpro 1009's. I've used them for years and never had a problem. Even on 12.5:1 comp. Used Cometic once and had water leaks with very good surface finishes. Guess we all have different opinions and experiences. The felpros will work. And for a 10.25:1 motor .004 won't matter at all. These aren't facts, just my opinion.
