We use the Trend tool steel lifters (without DLC) with as much as 550# open pressure on 0.842" lifters. We do this on nitrided cast iron core cams, and we do not use the EDM oil hole.

Thanks Alan for the response! It seems Trend are the way to go and have had a lot good reviews from racers. Have you had any feedback or reviews regarding there DLC coated lifters from any racers? Will definitely be in contact with them regarding correct break in procedures and oils. Does the latest comp cams finish have a particular name? Can you recommend someone to talk to at comp regarding this? Thanks
