the reason i ask is that i'm looking at a set of mahle pistons that i'm told are .030 over. i'm told they are for 98-2000 corvette ls1. i don't know if i should buy them or not risk my money.

Didn't you read the previous post. Anyone that tells you that they have .030 over pistons for a LS1 is full of bullshit. They may be .003 over - that would make them OK for a honed 98 LS1.
