Split Lobe Separation Angles?

isn't there an issue with using hyd rollers without bushing the lifter bores?

You can uncover the oil gallery. I think MRL has lifters that help with that.

If using a solid roller, you can either tube the passenger side gallery and block off the oil to tgphe drivers side at the number one main, or bush the lifter bores.
