The gasket was about half the size of the hole?!
Have you seen that before?I would have thought it would need a bigger jet not smaller.

It happens, not always, but the port work can make everything else so much more efficient, the smaller jet works better. It's usually about 1 outta 5 that happens with though, and a simple change in the pipe, air filter, or anything else on the intake or exhaust tract, could throw you right back up to a larger jet. usually we have to run sorta fat, because the head is so inefficient, as is, that is the only way to make power. A P&P job just brings it all together.
