Honestly I used the "George formula" with stock crank and rods, ARP rod bolts and Wyendorf lifter bushings, Ross pistons, Trick Flow heads, my engine runs fantastic and makes more power than I can really use on the street. I do however run 180 degree exhaust so I don't think the exhaust is creating much of a bottleneck. I did the rebuild work myself minus the machine work of course.
