Hey Mike, thanks for jumping in. I'm interested to look at the links you posted. I believe the heads that Eggman has are the same that are used on the LE9 305. And I think the compression ratio nets out between 9.2 and 9.5. I think that is why the electronic spark control came on the scene to retard the timing if the little motor started to ping.
