New pistons, boring cylinders

I finally got my new 0.5mm oversized pistons and rings, and all new valves. I brought the cylinders and heads down to Rick at RM Enterprises in Concord to get them bored and the valve seats grinded.

Couple weeks and I'll have the motor rebuilt!

#1 Cylinder corrosion

Got a problem here. Need a new cylinder!
Can anyone part with a #1 cylinder in decent internal shape?

Engine issues

I just finished painting my engine on Wednesday. I baked out the last pieces in the oven last night. I'll be putting it back together this weekend.
Big problem: I've got a corroded cylinder where one piston was sitting so long the rings rusted into the liner. I also need my valve seats grinded. Those are getting handled tomorrow morning, but the cylinder is still not resolved.

How I see it, I've got three choices:
1 - leave it as is and put it back together
2 - get a new cylinder or a new(used) one
3 - do a small bore and upsize rings... not sure this will work with just rings though

I'll have to post pictures and ask advice.
