Re: advancing timing
Yup -- it will help. It will help destroy the engine due to detonation. That results in holes in the piston followed by bits of metal floating around inside the engine followed by seizure and or parts exiting the block through large holes. Seriously, while one or two degrees of timing advance MAY provide SLIGHTLY better performance at the top end, it is not worth the risk and very likely won't be noticeable in the seat of the pants.
