If you're going splayed caps you may as well go SHP, a 4 bolt block can be had for the same price as a 2 bolt and it has added strength.

With a 3.48" stroke the support rings aren't needed, the 6" rod does require support rails on the oil ring with a 3.75" stroke, which is no problem and common for some engines, the pistons should be bought for metric rings so spacers are not required.
