Not sure either about the specifics regarding the port, etc.  I have never heard of anyone cutting a hole in one to match the original factory unit.

What I was told, however, was that Wiseco requires a different cylinder clearance and finish than the stock Honda piston.  That was from Eric Gorr many years ago.  If you have any doubts about fit or performance, pay a couple of extra $ and buy the OE part.  Peace of mind.
