Well not really because you should have the block and head tank cleaned and put new cam/main/rod bearings in with the rings. Doing rings also requires using a cylinder hone and probably a ridge reemer which would contaminate the inside of the engine too much.
Because of the transmission input shaft and flywheel, the crank cannot be pulled without removing the engine first. Lifting the engine out is very simple and makes it very very easy to do the engine work. You just have a few wires and hoses, engine mount bolts, trans bolts, exhaust pipe and lift it out with a rented or borrowed hoist.

You could get a full engine kit but if this is a real budget build I would inspect & measure your pistons/cam/crank first to see if they are too far gone. If you are getting an engine kit with pistons go to 10 - 30 thou oversize and bore the cylinders. The machine shop will tell you how big you need to go.
Now you are talking going full tilt rebuild for more $$$ and if this is not the original engine it just makes sense at this point now to look into the cost of a good quality used 6cyl of any year or buy yourself a an already built long block, see if you can save any $$$ and time.
