Put the lifters in, then the cam, and see if the cam can be turned! One person posted that it's a good idea in case you float a lifter sufficiently to hit the underside of the block. Mine are miles away (well, at least 1/4") at max lift so I didn't bother. But I do run a rev limiter

If I recall I bought that tool from a regular machine tool vendor. It is a fairly standard tool called a back spot facer or something like that. I think MSC has them in the catalog for $30 or something like that.

Thank you for your reply That's the one (316 adv/0.654", .024/.028 lash) P3690588 Mini-Express. I got a used one so I sent it to Schneider to have the lobe taper restored. They measured it at 278 @.050. After regrinding it was 272 @.050, .652 lift, .018/.018 lash so actually a bit more lift than stock and slightly less duration. If I ever get my Dart out of paint jail, I'll let you know how it runs!
