Edelbrock Performer Cylinder Heads 50169
^^^^
This is the assembled version of the Edelbrock head for the TJ. For your application you want it with valves and springs installed. It is a direct bolt on to the block. The reason you'd want this is that it is a +25hp bolt on. You might also consider 1.7 roller rockers to get a little more valve lift and about +9hp with a stock cam for $550.
You will need to have the early TJ 6-1 header OR a header instead the 2 piece stock exhaust manifold logs of the late TJs. I'm not sure which exhaust the 2000s got. Late manifold logs on the right below. My compatible headers left. I don't have an Eddlebrock head yet and could possibly end up go a different ported head route.

The newer style horseshoe intake is needed with the Edelbrock head, but I believe all 0331 heads have this. This is what the later intake looks like (air filter intake pipe removed)

Regarding the piston skirt, you can see the good example of a broken one above, but they could also just be badly cracked and making that noise. With the oil pan and girdle removed, you can see up into the back of the pistons. I took these while replacing the rear main seal. You need a torque wrench to reinstall the girdle.

I appreciate you taking the time to posts all this. Am I okay with just doing the head? Some of what you mentioned is probably out of my league to do on my own.
