Hope this is right:
Size Bore Stroke Rod
540 4.50 4.25 6.385
555 4.56 4.25 6.385
565 4.60 4.25 6.385
572
582 4.60 4.375 6.535
598 4.60 4.50 6.535
What heads are you going to run? I ran most of them combos and I liked the 598 best. also put the longest rod you can in it you would be surprised how close the oil rigs get to the bottom of the cylinder .
