The higher the compression numbers, the better.
If you see 350 and below your engine is pretty tired....

First and foremost inspect the bottom end mains and webs for any cracks, condition of the crank, etc.
Brake cleaner can help expose the smallest cracks.

If the block is good then work on upgrades.
ARP studs and gaskets, rocker retainer upgrade since you in there, New timing chain,water pump, Harmonic Balancer and Pulley, etc..
