Does this require attention?
While I have my motor stripped down I've been changing seals and cleaning and painting parts, pulled the camshaft off my turbo and each lobe has this blackish mark pretty much on the same spot on each lobe, what do you guys think? Should I have it reconditioned?
Each lobe has roughly the same size mark on them, should I worry or do something about this?

No, that's totally normal.
I've never seen a 944 camshaft without that marking on it.
Seems that when new the 944 cams had a surface treatment on the lobes to help with break-in procedure...because the lobe is offset slightly from the lifter (to induce lifter rotation) there is a little area that never got rubbed away...

Any thought on the tear down pics? The cylinders look pretty good?

Do you normally change the front bearings on the balance shafts?

I recomend replacing the front and rear ballance shaft bearings. And the front Sleeves with all new seals. Make sure you get the correct ballance shaft bearing. 86 and before have a different diameter then 87 and after.

I used a socket. Make sure you get the perfect size that pushes on the edge of the bearing without touching the inside of the bearing housing.

For the front bearing sleeves (the ones gripped by the oil seals) I just stuck a plastic-handled screwdriver in so that the plastic only touched the bearing sleeve, and hammered the screwdriver end until each sleeve slid free of the seal. YMMV

what are your opinions on this? Debating what to do, I think I scratched it removing the piston on the #3 cylinder, you can pick it with your fingernail, I wouldn't say it's a gouge more of a scratch,
Do you think this will cause any issue? Anyway to fix it without breaking the bank?

Fixing it would be near impossible (unless you want to have your whole cilinderblock done..) but i wouldn't worry about it too much..
Also depends on what your plans are, if you are going to get crazy amounts of horsepower, well.. Than i would recommend something else
