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.
