For an upgrade for performance above a comp 852 the Lunati Micro-trols and the compcams magnums decent for performance cams.

Wanting better quality lifters??? That would be these below:

Hylift Johnson part#A-0951

For higher performance cams (good choice on a RA4 duplicate)

Hylift Johnson A-0951R

For performance cams with adjustable valve terrain

Rhoads Vmax or VPro with superlube option (VPro-street)

Rhoads 9518P-super lube

Feels like I'm going down a rabbit hole with the valve train project. I called Len Williams today and asked him a couple questions about the parts I have installed. He didn't talk me into or out of Rhoads lifters, but he did mention that I should swap out the springs. Swap out the CC 995 for CC 988, he says that's what he installs in all of his long blocks. The 995 is matched with most Pontiac cam setups in the CC catalog with a few exceptions listing the 988.

Without getting into the weeds, the seat pressure is nearly the same, the open force for the 995 is 304lbs +/-, while the 988s are at 225lbs +/- at open.

I'm already going to upgrade lifters, but I have to make sure the rods I have are within tolerance. Tracking down Hylift Johnson A-951s is proving difficult, but I'll find them. Seems there's junk lifters out there for the unsuspecting buyer.

It has been posted here many times that member Paul Knippen sells the Hylift Johnson lifters.

Most here recommend the "R" version.

I have 2 sets of 16 new in the box Hylift Johnson lifters. These are the 4 per box B-0951 lifters available. $75 per set plus actual shipping. Bill
