An engine that needs more oil in the head (for what ever reason, like a head swap...) commonly starves the bottom end. Also when the head requires some volume of oil to engage vtec. If the galleys are bigger and vtec is engaged I could see it being enough to hurt a bottom end eventually from pressure drop at high rpms.

this seems like it makes sense... but if its 100% accurate, im not sure. the only thing i can think of is the fact that the oil pump either wasnt pumping enough, or that the pickup got clogged, or that it just all out failed. Either way, this is still a dark area for me. How could this possibly be prevented in the future, install two oil pressure gauges in the car to have one for the head and one for the block?

EDIT: also drained the oil out, and theres no metal shavings in the oil that i could see... its possible they could all be sitting in the bottom of the oil pan waiting for me though...
