Has anyone does this to an evo 8 head? Also wouldn't this make oil pressure drop? Since they're basically the same i was curious if evo members have done this.

considering these motors tend to fill the head with oil at high rpm, im not sure you want to improve oiling to the head in the first place.
I know i paid a decent amount of money for a custom piece to limit the oil flow to the head in order to prioritize the short block, they call it the kiggly hla.
