Speedmaster valve quality

The TF 2.02 is 5.200" long. The SM (Chrysler I think) 2.02 is 5.000" long. The SM 2.08 that I have is actually a Chevy +0.100 valve and measures 5.013" long.

They list those 2.08 Chevy valves with a 5.051 length. Interesting they are actually 5.013.

Thanks for the details.
