Mixed EDM Lifters

[middleagecrisis]

I recently purchased a nice used Hughes SB solid lifter cam with Hughes EDM solid lifters. Despite the seller's best effort to keep the lifters in order, the driver side bank got mixed up in shipment, while the passenger side stayed in place. So now I have 8 known lifter locations and 8 unknowns. I was planning to do the whole break-in procedure again but am wondering what to do with the lifters. Do I send them all off to get spot faced, just the 8 mixed lifters, or none at all if they are still properly machined? I plan on using the Isky Hi-Rev moly coating during the break-in. Should I just break-in the 8 or do all 16. I've broken in plenty of cams and never (knock on wood) had this situation before. Pretty disappointed in this situation, but it is what it is.

I'd send all of them out to be refaced. Small price for the insurance of a successful break in. 65

They should be stripped & cleaned AFTERWARDS because grinding metal will enter the EDM hole....

Either get them refaced, OR buy new ones. Either way, you will need to put the cam and lifters through a break in procedure as if they were new. @NC Engine Builder can reface them for you very reasonably. He's a good guy.
