I'm putting together a 540 c.i. GenVI. 4.245 crank-6.385rods-9.8 to1 compression. I'm wondering which heads to buy. My cam is a Crane 139671 HYD. Roller. Specs are @.050 intake 236-Exhaust 244 duration. 610-632 lift @ the valve. It's cut on a 114. Will be putting in a 70 Camaro 4.10 Turbo 400. Some street use. Thanks for your time.
