Replacing Lifters, What Else to Replace? I am replacing my lifters because it sounds like one of them collapsed. Since I am pulling the heads I wanted to do some maintenance on anything that I had easier access to. Any recommendations?
Things I already have:
145 amp truck alternator
Oil Pressure Sending switch (mine was flickering left and right and all over the place)

Get new lifter trays too. Also check the pushrods for straightness. And while you're at it (heard that one before?? lol) a new LS2 timing chain and oil pump (Melling high pressure, NOT high volume). These should freshen things up a bit for future use...

I have not decided between the Cadillac race lifters or just the delphi ls7s. There are a lot to choose from...

With only 30K (hard miles??) I guess the oil pump could be deemed optional. Up to you!

I would also consider replacing the intake manifold gaskets. The ones on my 99 TA were in poor condition after 18 years. Yours Maybe better condition given the low miles and being in Arizona. The ones on my car were a disaster waiting to happen give the car was outside in the rain on occasion.
It would have taken a while longer but one of those compressed less pliable gaskets was going to start leaking and allow the water sitting on the manifold into the 99TA's engine at some point.

If you decide to do the rocker trunnions, get CHE or Straub bronze bushing kits, though there are now others. They are the most well known.

I've been into three truck engines now, 1 6.0, 2 5.3 and have found wear on the pushrod tips at the rocker arm pocket, two or three on each engine. Should be a nice shiny mirror chrome look, these were hazy silver and had really fine scratches. Rods were not plugged, lifter end seemed ok.
