That helps a whole lot... Basically your shaving the sides of your intake/heads to match the gasket and when both sides fit the gasket they're matched (obviously)</P>
Is this about it? Also, I'd think shaving the insides like that would create an egg shape... Uhhh kinda like this:</P>
/ \</P>
/ \</P>
/ \</P>
Gasket Here</P>
\/</P>
\/</P>
\ /</P>
Wouldn't that hurt? Funneling the air like that cant be too flowful... Or do you shave far enough inside that it doesn't crate the egg shape, it just is straight.</P>
Thanks for the help on this so far guys</P><edited><editID>Milky</editID><editDate>37989.0761574074</editDate></edited>

Thet's the correct idea. You shave enough to match it out. Don't hog it or you'll loose low end power.
For every inch you go towards the port, a 2.5% increase in dia is beneficial (speeds up air flow), any more won't help. Or....go from the port and decrease 2.5% for every inch untill you reach stock size.
