I bought an AAZ trying to comp test, what starter to use?

All 3 of my MK2's had gear reduction starters, and they're not nearly as big as the "direct drive" that my 84 and 83 had.

I prefer a leakdown test over a compression test, especially if there are any issues with cranking the engine over.  Better info and easier to perform.

I agree with you here libby.

I tested the engine again tonight after putting pb blaster in the cylinders, seafoam a few days later and then filled each cylinder with about 2 cups of diesel and let sit for 6 weeks, then changed the oil.  I fear I may have let it all sit too long and possibly ruined some of my hopes for improvement.

My numbers are only slightly better.

Original: 300, 360, 330, 280
New: 380, 380, 300, 300

This was on a mediocre battery.  It was tested as being good, but definitely not the same one used as before.

Seeing how the test showed slight improvement I am going to just tear the engine down and give it a good rebuild, maybe re ring it as well.

I used approx 2 feet of 2 gauge wire from battery to starter unlike before using 12ft jumpers.
