Stock stamped steel rockers, took the push rods out and rolled them on a flat piece of glass and inspected the tips for straightness. I have a autometer A/F meter hooked to left and right banks through a toggle switch so I can monitor each side individually and the fuel pressure gauges are mechanical under the hood and electric inside on the a pillar next to the A/F gauge. A/F under WOT used to stay in the green gradually climbing until shifting, now it goes green, but stays steady not climbing so it makes me want to look at the fuel system as well as the lifters. A friend brought up to me about the fuel filter. I got a new one to put on...just havn't done it yet. BTW, on the autometer gauge, red is lean, yellow is styochromatic, and green is rich
