Looking for 360 advice on a budget.

Ok I typed a big old paragraph and it disappeared so this one is short and sweet.:bootysha:

On the rearend I already have a couple 8 3/4" rearends that I plan to use to put in the car.I know I need to get a lower gear than what I have as this car is heavy and needs all the help it can get.

I also have no problem trying to pick up a set of pistons if I would be better off.I need to get the engine tore down and mic the cylinders to make sure I don't need to get it bored.
I agree with what was said on the head gaskets.I plan to get the thinner compression distance ones.
I will try and do a redneck cc job on the heads with a syringe to see exactly what I have. catch you guys later when I get back in from the shop.8)
