Old school engine rebuilding wisdom welcome here

When you balance and engine, which is very cheap to do, you balance the crank, rods, pistons, rings, flywheel and balancer. It is WELL worth the money.

As far as a roller cam, great choice. Crane, for one, makes a retro fit kit that fits a reduced diameter roller cam to your block. I have installed several....and they work great.

Cylinder heads, well I'd save my money on working the stock heads over. Go out and get a set of Elderbrock or another. Well worth the money and darn near the same price as working you old stock head.

I wouldn't restict oil anywhere. Leave the oil route stock.

You usually go .030 over to clean up the bores and get the most cu in for the buck.
