SB Crane Retrofit Roller Lifter Issue

I,too, have these exact same parts,and questioned every MOPAR site I could find to no avail. I had Delta cams in Tacoma cut my cam down from a 699641 to 621 specs.I just put the bottom end together last weekend, and the cam in today.I only dropped 2 sets of lifters in to check the fit, and both were well down the lifter bore, with at least .200" to the galleries. If any one is interested, I'll put all the lifters in and take some pictures to post. Just FYI, my block is a '70. Paul
