Steve, thanks for the feedback.... All valid points. I think you might be the one of the few people in the SCCA who could have someone legitimately disqualified and sent home having absolutely no idea what they were just disqualified for!
On your "pop quiz", I really don't know, but will guess exhaust side retainers on diamond wire intake springs?
Matt, Thanks also. In all of the times we have been through tech inspection, I have never seen an inspector use anything other than a digital caliper. It's definitely the wrong tool for building an engine, but what they're really looking for are oversized pistons, which will be at least 0.010" (0.25mm) oversized.
