A good, round cylinder w/a piston that has the correct piston to wall clearance, along w/the correct ring end gaps will do as much for performance as a LOT of other "racing" tricks. What guys fail to realize is, while a loose piston to bore clearance may have less friction, the rocking motion this allows causes the ring seal to go away.

Follow the manufacturers specs for piston clearance, ring end gap, etc. Measure the piston where the manufacturer says to measure it.

Use a three angle valve job. Backcutting the valves is sometimes a cheap way to increase flow where it'll help on a day-to-day basis (look at what GM did w/the Vortec valves- they do NOTHING "just because" ).

Break in the cam correctly.

There are other things but these are fairly important IMHO.
plate hone, with bolts or studs being used on engine, and main caps torques if poss.
