lifter galley crossover tube

I bought two sets of the "H" series Mahle Clevite to get the full groove. The groove on these newer bearings are not as wide as in the past but, depending on who you talk to a narrower groove is better. I opened the oiling holes myself to improve the flow.
As far as I know , no one offers a bearing with the opened up oil hole. My bearing holes were enlarged with an edm machine.&
