I searched the web and came up empty. I put a snake cam down the cylinders of my 01 Cobra and I have what appears to be flat top pistons. I thought they had a small dish and only mach 1s had true flat tops but I guess I could be wrong.
I only see a part number on one which is odd or maybe just a lighting issue.
