If you haven't ordered the lifters yet, I would highly recommend lifters that have a small oil hole drilled at the bottom to help oil the cam. There are others that have a flat area to help lube the cam too but I am unfamiliar with those. Lifters with oiling will provide insurance against wiping the cam.
Also, as other have said, make sure your lifters move extremely easy in the lifter bores. Any "stickiness" at all is bad, and can cause the lifter to not rotate and wipe the cam. A good test is that when lubed up, a lifter should not stay in any position you place it in. It should just fall due to gravity all the time. Anyway, I am probably beating a dead horse here, but clean, good lifter bores are CRITICAL so an engine doesn't wipe cams.
Good luck

Anyone who does NOT use a break-in lube will automatically receive holes in the bottom of the lifter. Free of charge.
Please be advised there could be a delay in receiving your 16 holes, but your order will be processed as soon as possible.

Gigantic price difference if you use good parts to do that right
