I'd leave the sixpak rods in the pile. By the time you resize them and buy good bolts, you have paid for most of a set of H beams that will lighten up your bobwieght a ton.
Another vote for a stroker. 511 cubes will hit your number by accident. If you are stuck on using iron heads I'd use 915's and build it zero deck for quench stroker or not.
A stroker with Stealth heads would do the deed at 9:1 on 87 regular.
