If you install 72cc heads the compression ratio goes from about 7.5/7.7 to 1 up to at least 10 to 1. That is a HUGE increase in static compression and with that tiny little XE262 cam dynamic...

Since you are making 16" vacuum at 750rpms' with 11 degrees initial timing there would be no benefit whatsoever to add more timing at idle speed. Matter of fact it may not work nearly as well as you...
