Same thing on drilling out the inlet in the cylinder. Go very slow. Stop before the bit gets to the actual opening in the cylinder wall. If you drill through into the cylinder port itself you can upset the port timing. It is OK to widen the inlet port a little but don't raise the top. After you get close, use a dremel to smooth up the transition.

You will lose acceleration but gain some top end.
