Head flow and power differences question / discussion

My 360-1 Indy headed engine and my Edelbrock engine have both gone 5.98 with my son driving and 6.0 many times with me driving. The Indy engine had a .650 solid lifter cam and the Edelbrock headed engine has a .650 racer brown roller cam. Both engines have room to grow cam wise. Both engines will have better heads next year. It’s like baking a cake. It’s all about the right ingredients.
