Objectively: as for me Aluminum heads are developmental.
Iron heads are reliable. I'd like to see the "best developmental head" be revealed, then cast in iron, then availed in JEGS or Summit as affordable. |

Ask Jim Sammons about that, he will tell you the lowdown on what it takes to bring a product to market.

"Your street builds have always been impressive to me, after all I am a street car guy that was forced into racing just to prove a point."
Thanks. Been an avid racer for decades myself....I just have a LOT more fun with a "daily driver" that I have to slow down to stay roll bar legal with. Nothing funner that I know of that pitting beside some guy with a gutted out Camaro or Chevelle with every part he could afford from the high performance parts catalogs, including a big hole cut in his hood to fit two 4bbls, and we're running faster than he is with full exhaust, quiet mufflers, no bars of any king, and stock Ralley wheels and trim rings! The icing on the cake is when they wonder over and see the q-jet sitting on the stock intake......priceless!......Cliff

Do not know how many Ram Air IV and '71 455HO heads I have seen cracked and they are not easy to fix. '72 455HO fair better because of their larger cooling areas and tend to crack much less.

Us cold-weather folks do concern for valve seats that rattle loose, head gaskets that wear out, sparkplug threads that strip/cross easily when we tighten til it gives & back-off that 1/4turn. Things like that. |

I bet that anyone making a good aluminum head, then casting the same head in cast iron, would not be saving you much money. The additional cost of aluminum is not that much, it's all the developement, the trial and error, the casting costs, the advertising and then the maker has to rightfully make a profit or, why do it. I wonder if any of the Pontiac head manufacturers out there could give us cost difference if they offered a aluminum head and an identical cast iron head. Be it would not be that much. I could be wrong but that is just my opinion. I also agree totally woth Steve. The aluminum has so many advantages over the cast iron. As long as they are designed as an aluminum product form the inception. Mark L
