Anyone using holley alluminum heads??
I was browsing the holley book and work and noticed I can get a set of holley alluminum heads for 800$ with my discount.
They have 175cc runners, 220cfm intake flow and I think 185cfm exhaust and weight 30lbs each. These could be the ones used into the system max kit im not sure.
Thinks these heads are good? oo they are 23 degree heads also with 69cc chambers
