    What bore size would these fit?

      In the picture, it states +1.00mm on each box and they are domed.

        Right, but what engine is that a 1 mm overbore for? 3.1, 3.4?

          that shows them being specified for the 2.8 w/1.0mm overbore.

          EDIT: it also specifies to be used with gen1 heads only?

            these are for the iron heads people.

            if you have e85 in your area, then I would find a 3100 block for the roller cam only, 2.8 crank, these high compression pistons, port out some iron heads, and pick up a iron head itb that stalkerv6 is about to put up for sale on here. 250 hp should be doable with that setup.
