I have searched through the forum concerning
oil restrictors and was wondering if someone would take the time to explain what they are. I am using OEM 390 heads and have a Melling HV
oil pump. Like others I have read about, I think I am getting too much
oil on the top side. Can they be installed without removing the heads? Where do I get them, what size do I need, and where exactly do they get installed?
As always, I appreciate any input.
