Choice for EDM solid flat tappet lifter.

OK, fair enough. Would that negate post #2?.
This is the SB section, not slant6, which do have pressure fed lifters.
Why would it negate post #2? The Camsavers, while they'll fit and work in the slant 6, won't function, since there is no pressurized oil to the lifters. But again, YOU said ANY lifter and you were wrong.
