Solid roller lifters...

Oh, and I spoke to Brad from BAM about the axle oiling.
As it turns out the oil holes just above the axles are the “auxiliary” oiling holes, and that there is a small hole edm’d from the cavity in the body to the area just above the wheel.
It’s there in the drawing I posted if you blow it way up and know to look for it.
That looks like one EDM hole on one side coming down..And yeah, overlap can cause issues with idle AFR readings.
