5.3 ring and bearing job

[buds56]

I got a cheap 5.3 for my 61 project that had a small ticking noise which showed upon pulling the valley cover a bad roller lifter and a cam lobe wearing. this engine ran fine at least 40lbs of oil pressure, no smoke, no coolant use, 150k miles.

I bought a gasket set, head bolts, stock cam, lifters.

Pulling the cam out today brought out a damaged middle cam bearing.

So the engine needs to come apart for new cam bearings and a thorough cleaning, cylinders look like new.

Can I just "ring and bearing" it?
Using the pistons and rods over again, stock rebuild.

I would just get a wrecking yard engine but I already bought some parts.
Thanks,Bud
