[Vwdiesel] Should I Re-Ring?

Background: 82 Stock-ish 1.6NA - 2yrs+35k on bored +1mm rebuild.  Lost
coolant at 10k, lost oil pressure at 34k.  Still running.  Was running
hot on hills under load, replaced thermostat and radiator, helped (like
perfect) for a couple weeks, now running hot and cold every couple
miles.  Oil in coolant, replaced oil cooler, coolant tank stays full.

Plans: replace head gasket, swap oil pan for a turbo pan (a delayed
project) and install new Peloquin trans coming this week from
AATransaxle.

** Compression 400,345,370,400 (HOT), 450,390,440,450 with a spoonful of
2-cycle oil.  Is a +50psi with oil sealing like this expected on normal
rings, or would there be a benefit (or disadvantage) to putting new
rings in? 

Probably should have replaced the headgasket a long time ago, but my
compression tester was broken, and it HAS been driving daily (though
just on local roads, not the highway).

SHOULD I RE-RING?  I'll have head and pan off anyway, but it would be
in-rack with crank in.  I have another engine to rebuild when this one
dies, but I would really like to get this one in shape for summer.

Thanks for you opinions!  I have disassembled a bunch of parts engines,
but have never done rings or put pistons back in.
