I tend to go with the Morel lifters if your going to run an .842 lifter as they are to OEM size. ISKY, Crower and Comp lifters run to small to put in an OEM lifter bore.

I have found that ISKY lifters have alllllllways had a sizing issues some times it has taken up to 3 sets to make up one set to get the sizing correct, Do a simple search on this problem.

If your dealing with an old GM casting you may find the lifters maybe warn do to push rod angles.

For a more dependable lifter go with a .904 lifter bigger body, axle and with the .810 wheel less revolutions around the lobe.

What ever lifter you buy measure every lifter and check each lifter bore for the proper clearance.

Good luck which ever way you go.

.0014 to .002 is what I shoot for and has been working for me so far. Its really not a Chevy lifter its more of a AMC lifter.

He is a good video to watch as there is no standard on sizing between roller lifter companies
