I would rather have shaft oiling. But my 2000 360 magnum engine the block is not drilled. So I have to run push rod oiling with my trickflow heads. I could be wrong, but I only know of three Rocker company's that have push rod oiling capable rocker arms. That is Harland sharp with 1.6 not sure if you can get them in 1.5, PRW 1.5/1.6 and Comp cams but they only are offered in 1.5. Now the difference rocker ratio might not bother some people, But I wanted to run 1.6 so I am useing the PRW 1.6 rockers . I too am useing the ARP head bolts. This is the first time I have ever used push rod oiling with LA heads. So it's new to me but so far I haven't had any problems with the set up.
