You may be going about this the hard way. Let's find out what we MUST work with and then determine what we MIGHT ALSO work with. .7854 times 4.04 times 4.04 times 3.48 times 16.387 tells us that the cylinder volume is 731 cc's. We already know that the chambers are 72 cc's. So, we have 803 cc's that we can't change. Now, let's find a volume for the valve reliefs, piston deck height and gasket volume that we can equal 9.5:1 c.r. with. If we add 731, 72 and 14, we get 817. If we add 72 and 14, we get 86. Now, if we divide 817 by 86, we get 9.5:1 static compression ratio. So, somehow, we need to use a piston deck height volume, piston eyebrow volume and gasket volume that will equal 14 cc's. Now, on a flat-top piston, the eyebrows are usually about 5 cc's, so that leaves us to come up with 9 cc's. A gasket with a bore of 4.100" that compresses to 0.040" will contain 9 cc's. OK, we're there. That doesn't leave any room for piston deck height, so the block will have to be zero decked. Just by the luckiest of coincidences, we have arrived at the perfect static compression ratio and also the perfect squish figure (0.040" @ zero deck).

Hurray for our side !!!!!!!!!!!!!!!
