Used pistons usually have carbon deposits in the ring grooves. If you put new rings on the pistons without cleaning out all the carbon, the new rings will probably be too tight in the lower part of the cylinder bores, especially if any of the new rings needed needed their gaps corrected.
An engine with less that 50,000 miles should not need new rings. Your engine may have had stuck or gummed rings.
I would not start the engine with a used head gasket in place, and I would not start the engine without finding out why it is so stiff. Starting the engine with mis-fit parts could do major damage in a few seconds.
