Default Identify these heads

I got this pair of "Stage 2" heads or so the guy called them. They are fully cnc'd, 2.02 valves, dual springs, ect. He forgot who did the work but someone out west he said. i recieved flow sheets that he had done a few years ago to see what they did. Im hopeing someone can recognize where the numbers are.


The 003 is to identify the pair I would assume

This is the only other non factory number I could find

Im gona cc them to check, and im throwing them on. Would be nice to know who did them but not totally necessary. Thanks
