Another option you might consider is using your old biral cylinders. You can have them bored/honed to oversize and get new pistons. You of course should find the pistons first! This might be cheaper than buying new P/C set and would keep you with steel sleeves to assure long case life. If you are going to do new P/C set then I agree with Grady about the 2.7 conversion. The engine will look exactly the same and have so much better power/torque. It looks to me from you're picture like you have time certs installed. I would think that the shop that did your machine work should be able to confirm this.
