Strange that one of your old plugs looks like it's copper but the other ones are not.

AC Delco "Professional" is aftermarket. In my experience, it's a "good" aftermarket, and oftentimes is just reboxed Moog for their suspension items. That blue boot look familiar? (Moog Problem Solver)

AC Delco "Original" is what is on there from the factory and is usually the most expensive, but is reliable. AC Delco "Professional" is an acceptable aftermarket aimed at a quality part for a lower price than Original. "Advantage" is aftermarket that caters to low price and sometimes quality be damned.

Thank you for the clarification! I thought the blue boot looked familiar.

I think it will be just fine on a lowered 2wd with small tires.

Interesting!

Steering is all finished up as is the wheel bearing and fresh TR55 plugs to replace the random assortment of TR6s.

Steering feels a little tighter I wouldn't say its night and day but it was never really "bad" before. Only thing I don't like is I got a AC Delco professional grade pitman arm and it seems considerably smaller than what was on there which I'm 99.9% sure was stock however, I do like the better quality blue boot.

Plugs were a little oily but I don't remember if I ever got them real clean when I installed them with the new heads.

Anyway happy to have my girl back on the road. Got all the coilover measurements I should need while it was apart too.


P.S. to myself in the future this was done at 258,997 miles.

Not a Delco fan when it comes to plugs I see. We ran NGK's in our sleds.

When I had the valve drop and the heads went to the machine shop they stole my like new tr6 iridium plugs. When I thrashed to get it slammed back together I realized it was to late to run to the parts store and get new plugs and I wanted it running that night so I scoured my old parts boxes and came up with what I think was 7 iridium from the previously boosted 4.8 on the floor and then 1 random plug from IDK what. Brushed um, gapped um, gave um a brake clean BJ, and threw um in while telling myself "Ill order new ones tomorrow". Never had any knock issues or weird misfires.

Always have run NGKs in LS stuff, I guess because LS1 tech seems to like them the best.

And I, “ like my oatmeal lumpy .....”

Oatmeal is yikky, grits are the best.

Creaky, groany, haunted house noises from the front end are still haunting me. Pretty much the only thing left is ball joints which certainly aren't fresh but don't appear to have any play or make any noise from me wiggling them around.

The problem is if I do upper ball joints I should really just do loaded UCAs cause it's easier. If I do UCAs then I need an alignment which is kind of a waste because coilovers also require an alignment. 2 alignments are more expensive than one so the solution to my groaning steering is a coil-over swap down the Randy rabbit hole of "While I'm in there might as well do XXXX".

Say what!?!?!?!?!?!? My silverado coilovers don't creak. My current creaky polterguiste is low speed steering only so its 99.9% the ball joints I think.
