I'm with John on this one. Tightening the piston-to-head clearance to the minimum safe distance has a huge effect on squish/quench and therefore on burn rate. A fast burn rate makes more power more efficiently, and allows higher compression for any given fuel octane rating. It's one of the things that wasn't properly understood back when the B18/20 was designed, and it's very easy to correct. I wouldn't consider not addressing this even in my lowest-budget engines.
