Re: high conpression head ??
Regarding timing with high compression head: I set my distributor with the lever 3 notches down. I drive with the lever about horizontal. This has another advantage in that you can idle the engine way down by moving the lever all the way up.
Regarding high compression head design: The area where the air/fuel charge moves down into the cylinder has to be carefully designed. The roof has to be raised and a large radius provided. if this is done the compression ratio can be raised beyond 6.5 to 1. The custom V8 heads, shown below, illustrate the idea.
