Oh lawd, haha.

Dynamic VS Static compression (this has alot to do with octane):

More DCR info:

It Is important to understand that DCR is not the be all end all in determining weather your engine will run on pump gas it just helps more than static because your taking into affect the valve events. VE, Attitude, temperature, and the tuner have alot to do with making sure your car will run on pump gas.

Combustion Chamber sizing (in relations to piston shape):

Search, Search, Search and Search. There is so much good technical information out there not just on this site but others that it will keep you busy for years if your interested in learning it. There is enough practical experience and sponsors that do enough of this stuff to where you can get ideas for a strong running combination without to much back breaking research and calculating, if you find yourself getting lost in a swirl of information.
