Good afternoon to all. I need some information on which head gaskets and Quincy for my sb. I am installing 64cc promaxx aluminum heads on a 355 with summit hyper pistons that are 1.56 compression height. Stock deck and my best measurement is 0.25 in the hole. Stock. I have a 1094 0.15 gasket which should give 40 quench. I also have a victor 0.26 grafite that would give a 0.51 quench. Which would you use and why? Can't decide. Help appreciated.
