What is the difference between a 302 and a 302 ho?
As I understand it, the standard 302 is a non-roller engine, meaning mechanical rockers, while the HO is a roller engine, having roller-rockers. Roller-rockers have a bearing at their bottom that allows the rockers to move more freely, without the dragging of the mechanical rockers. Hope this helps.

Does advancing timing raise idle?
It will produce less power(torque) off idle and rev slower. Advance timing, and response increases, easier to start, more power(torque) off idle. Some engines use the vacuum advance to advance timing at idle.
Does advancing timing lean or rich?
Lean mixtures burn faster than rich mixtures and they tend to produce more heat. Richer mixture needs more timing to completely burn and they tend to produce less heat. Too rich will cause knock, too lean with too much timing will cause knock.
