George's number for other blocks explains a lot. I cut .016 off the last block to get zero deck.
Just note something I learned from Scat - just because the numbers work out doesn't make it a viable combo. I asked about the same thing with a neutral balance, Scat tech said "won't work - rod too short to balance". 6.125 rod, custom piston. Just keep that in mind.
