Dumbutt Question.....

I never looked into running solid rollers on a slant, so I have no personal experience, here. Why not just run the stock type solid adjustable rockers and pushrods? I wouldn't think you need to get additional oil to the lifters, then the splash oiling. Look at what they do on small blocks when using rollers, they install a tube in the main oil gallery, which blocks off oil to the lifters. There are a couple of oiling mods some slanters do for additional cam lobe and lifter oiling. They cut a small vertical groove, down the lifter bore, and install "standoffs" in the drain holes in the lifter galley. There were pictures of these mods on slant six dot org, but photobucket screwed that up.
