Thanks:) Don't call em wallet stealers for nothing!
Last 26 I built, did the head oil restrictor, enlarged oil returns at the back of head and oil return holes, mines head baffles.
Wasn't enough, especially for track work, and due to ring gap being a little big, more blowby than normal which meant oil being forced to stay in head/get pumped into catch can instead of draining to sump.
This time, I have only added a tomei sump baffle, rest of engine is completely stock, save for ACL bearings. I have read the oil control thread too and chose not to do certain things.
And yes, head drain kit is on the way!

Still have to get a decent baffled catch can too.
