Pinging/Vapor Lock?

It degreed in spot on. But went with the advise from other members to advance cam. So from the 108° went ahead 4 more degrees. Timing well just set it to 14° or 15° initial. 34 total degrees timing.

Ok good deal. Thanks for clearin that up. Ok so the KB107. It probably has "around" a true 9.5:1. So assuming that, I would start with about 15 degrees initial timing with about 36 total all in by about 2500. You'll likely need one of those limiter plates from Don at FBO so the total doesn't end up too much. Just a place to start. Also, You should run a compression test. That average number can give us a clue to compression ratio as well, since we know what cam you have.
