In port reshaping, you are changing the engine design in a fundamental way by changing the size and shape of the intake and exhaust ports - and hence the flow rate and timing of the engine.

This is a no-man's land of cracked rings, seized engines, and 'tuning' a perfectly functional engine into a boat anchor with a single stroke of the rasp.

Seriously, unless you have a bunch of spare cylinders, you don't want to do this. For a more gentle engine modification, see port matching.
