I do like the idea of going over .040" and boring the cylinders over to suit. I originally planned to (and still may) buy Tlowe's pistons as I appreciate brand new items with modern fabrication. Also they are readily available, which seems to be the main problem with this NOS stuff as it's obviously hard to find and I'm late to the race. For quick reference, I've made a list of known compatible flat top forged pistons:

L2314F - high compression 307 pistons (+/-$250)
L2402F - low compression 307 pistons (+/-$250)
12bolt's Ross 250 pistons ($600)
Sissellautomotive's 250 pistons ($625)

The list is currently in priority purchase order. If it gets close to rebuild time and I haven't found a good NOS set I will definitely get the 12bolt set. They probably are the best quality choice (even tho I know nothing of Sisselautomotive's product) but this build is going to have inevitable cost issues and I need to be cheap whenever possible.
