I have four pistons @ 1.722" CH and four @ 1.723". Once I have checked all the rod throws for stroke length using my test rod and one piston, I can do a dance with rod length, CH, and stroke length to get all deck heights as close as possible. It won't make any difference on the stamped rod number as I may use it in a different cylinder number (i.e. #1 rod in place of #6). Then before the balancing is done I will machine each quench pad for a specific cylinder depending on the deck height. After the dance if #3 piston is .003" lower in the bore than #7, I will leave the quench pad .003" taller on #3 than the pad on #7 piston. I can do it this way because all the flats in the head combustion chamber are all .110" below the head face.
Even though the flats are all the same in the heads, the combustion chambers are a little different in cc's. Because rod #4 is so short I may shuffle it to a combustion chamber that is smaller in cc's than the others to attempt to balance the compression ratios from cylinder to cylinder.
Still clear as mud right?
