For those of you who are going through the costs of porting and polishing, adding larger valves etc., don't fail to give some attention to the two cylinders that tend to heat up more than the others due to water passage restriction. A little work here will enable sufficient coolant to prevent heat build up and the resultant pre ignition problems.

[QUOTE Drilled for 12mm head studs.

I didn't pick this picture out for the head studs. I liked the shot because it shows the webs or crank supports. Notice they come stock with square edges. In the following pics it shows the webs rounded or "bow tailed." The purpose is eliminate windage allowing the motor to respond faster.
