Which heads to use, Dart AFR Canfield Edelbrock? Alum. or case iron? Alum. would keep cooler but could you put more miles on a iron head and would iron be less maintenance as in valve guides and seats?
Also dual plain intake or open plenum,4150 or dominator? Eagle rotating,callies etc?
I would run the brodix bb-4 heads or the dart 355s on the big ci motors. alum heads are fine for street use I never seen much difference in maintenance between the two. I never ran a duel plain intake on my big motors just the single plain with a dominator . callies or Briant will hold up to more power if you have the extra cash.hope this helps
