"Your crank, rods and pistons stack up to 9.001". The block is 9.025". This will leave the piston 0.024" down in the hole at TDC and won't do much for squish if you use a conventional gasket of around 0.040" thickness, resulting in a squish of 0.064". If it were my motor, I'd use a Fel-Pro #1094 shim gasket, 0.015" thickness, to put the squish at 0.039". With 731 cc's in the cylinder, 77 cc's in the chambers, 3 cc's in the gasket, 5 cc's in the deck and (negative) 3.5 cc's in the piston, your c.r. would be 9.96:1 and the motor should run well on premium pump gas with the tight squish. I'd run 12 degrees initial lead at the crank and 22 degrees of centrifugal lead, all in by 3,200 rpm's."

Do I need to use any kind of sealer on the above recommended gasket--Fel-Pro #1094--when I put it on or can I just put in on dry, and then lay the head on top of it, and torque it to spec?
