rebuild suggestions

ok, since I know that my cracked block wont last forever glued together.

I am looking for direction on rebuilding the spare. don't want to go broke rebuilding it so the pricey rod/piston combo are out. mostly a cruiser for the street.
is a re-bore with stock style replacement pistons and milling the block ( .120 off the current )my best option?
I have a Ported head, Hurricane intake and Clifford header on the current engine with a erson cam. 904 with a decent stall. Hoping to reuse most if not all of these on the rebuild.

Thanks!
I didn't want to have to yank an engine after I had redone the car so that's the way I went. no fancy combo since I'll turbo it after I get some (2000) miles on it. I really want to drive it some before I take the exhaust apart and replumb it again
I re-did a good used engine but it had some miles on it and one of the bores was tapered too bad to save without a rebore. sooo. .030 over pistons cost me a whopping $93. crank was okay and I just cleaned it up decked .100 to get the pistons up a bit and ended up with a total cost of 450.00(including pistons and rings). I bought the gasket kit (don't remember the exact price but under 100)and brought it to the machinist to do my valves and seals , then I ended up adding getting the head done by installing seals and bigger valves. took .060 cut to flatten and raise compression that added another $325.00 to the cost including me ordering the valves I stayed under a grand so far, well maybe I blew it since I got the cam reground by oregon grinders to the #819 grind. so I might be over a grand now. your head work will cut a lot of the price off a rebuild since you have already put out that money. I'm getting ready to add the lifters and head next weekend after cleaning up the mating surfaces.
