The "band" type compressor is what I use when all else fails ! It is a pain sometimes, but it does work. You have to have it VERY tight, and hold it tight against the block. I use a large (3 lb) dead blow hammer to tap the pistons in with, I hold it upside down and use the end of the plastic handle against the piston. Also...the ring compressor does have am up and down side...make sure it is right.
The other possibility is that when the block was bored...if it was...the machine shop did not put enough of a chamfer on the top of the bores. Without it, it can be almost impossible to get the rings to go in.
The solid, tapered ring compressors actually work the best most of the time, but you have to buy a different one for each bore size you are going to do.
Hope this helps,
