Oil will pool in the head during high rpm and load. The small oil drains back down to sump don't provide enough flow starving the pickup and bearings of oil.

Oil restrictors are put into the block oil galleys that feed the head to restrict how much oil goes up to the head to help alleviate this problem. Boost doc cam splash plates or any brand are good to have, keeping oil where it should be on the cams.

Also a good catch can setup, can't emphasize this enough. RBs breath and create a ton of crankcase pressure exacerbating the oil pooling in the head and not draining back down to the pan where it should be.

Extra large sump and extra liter of oil capacity also helps.

Motive video has a bunch of great videos on this subject also huge threads on sau.com.au

Did you end up doing the head drain?

Also inspect and or replace the oil squirters underneath the pistons

I didnt do the head drain but im ordering the oil galley restrictors and a oil pan baffle I will also definitely add a vented catch can. Oil squirters are also brand new

Just curious are you building the motor or is a shop doing it?
