your going to have to notch the morel lifters, i have not used any yet that i didnt have to, just remember the bigger the notch the more the oil. i dont feel those lifters or just drop in and go lifters.

But....my block was honed to the correct clearance.

Morel intentionally manufactures their lifters with a lifter body diameter that is on the high side (those which are sold under the Morel brand name). They do this so that the performance engine builder can size his lifter bore clearances exactly where he wants them, just like sizing the pin end of a con rod, for example. It's intended as high-end application stuff. If you don't set the lifter bore clearance, you may not get adequate top end oiling.

New blocks will need to have the lifter bores sized, and used blocks often need to be sized...or you can lightly notch the lifters instead of honing the lifter bores. (Another nice thing is if a used block's lifter bores are worn a thou or so, the Morels can "compensate" for that in some builds.) I think it's great that we have a lifter body with alkl of this in mind, and from a high quality manufacturer.

And Morel makes some very high quality lifters. People who use them and companies that offer them under their own brand name include: Force, Roush/Yates, Hendrick's, RCR...Isky, Crower, Merc, Lunati, and more.
