I got a new head and it is missing a tap on the inside where it looks like a pressure release valve? Used to go in my head. Corner driver's side on the exhaust side of head.

i believe it does not, by the pics i have it does not appear to go all the way through, though it may tap into the little passages in the head. It's an accumulator, so i would say it's definately oil related.

have a peek through my album, there's a few other pics of the head, you just have to snoop around

Yes you are right, it is an oil pressure accumulator. It absorbs and releases oil pressure at a spring controlled rate -- it does not pass through to any other oil passage-ways.
It eases oil pressure shocks when the MIVEC oil control valve opens and closes. Without it, oil pressure would "slam" into the MIVEC system.
