No, this is not Psych 101. This is about my 750.
I took out my engine this weekend (ow, my back..) and disassembled for my next rebuild (MAN, that head was stuck!), and thought some of you might want to see some of the insides of my 100,000+ mile roadraced/toured engine, or parts of it, anyway. Here's a picture of the combustion chamber (#4 in this pix). Those of you familiar with these heads might say, "Huh?" - it's missing some things, like valve shrouding ,charge mix ridges, and (visible) some metal in the intake tract. The head has been partially hemi-ed and the ports raised, widened and smoothed to match the throats of the 28mm carbs that feed 'em. The compression in this engine is about 8.8:1 with stock "K" pistons, stock head gasket, stock cylinders and stock cam at stock timing. The CR was closer to 9.0:1 in this particular engine because of cam timing changes.
My new plan includes milling this head for a "stock" CR of 9.2:1, possibly decking the cylinders if the pistons will allow, and modifying the quench zones for more turbulence and directed charge flow at the plug, a la the Magna series engines. It will also become fully hemi-ed, the valves will be polished (since I don't have inspectors looking over my shoulder anymore) and the intake ports will be smoothed and raised some more. The cam plans will become whatever I can find...
