valve covers I don't know how the Katech valve covers will fit. If you were to run either those or our race valve cover, It would be a good idea to mill the valve cover rail down a bunch. I have milled them close to an inch and with the undercut in the valve cover, the rocker arms sit up in there and you gain the height clearance in the car. The reason the valve cover rails are so tall to start with, is that they were raised to be able to use a stock valve cover with stock rocker arms.

Cary, John, I run the etp4.1 heads and katech covers using crower shaft rockers. Things are tight, but they fit w/o milling the cover rail. I just had to make a couple thou more clearance at the cover for the pushrod end of the rocker. The katech covers have reliefs for them, u just have to kiss them a bit w/ the high speed grinder and nothing touches.Hope that helps
