Welcome to Bulltear! :!:

1) Should I even bother with re-using the timing cover and pump?
2) What should I examine on each to determine if it's re-usable?
3) Should, could I rebuild the pump / replace it?
4) Any other mods that could be done to the engine itself as far as oil passages and oil pumping goes?
I'm sure other will chime in, but here are my opinions.
1) The factory cover is probably the best bet. You know it's worked before with no problems.
2) Remove the oil filter adapter, look for any deep scoring on any of the surfaces (top, sides, and cover). If everything is still in spec, no reason you can't re-use it.
3) Bulltear HRC gears are a good replacement. It's not a bad idea to replace the relief spring as I have seen them weaken with age/heat.
4) Either the Bulltear cam bearings with the smaller oil hole, or pushrods with smaller holes to reduce oil to the top end and increase to the rods/mains (not both). Replace the filter adapter with a newer one that doesn't have the bypass (that's the little valve right under the filter stud).
