We had this discussion about a year ago, and Joe Hauser pretty much put it to rest. The alum.head has better heat dissipation, not worse, than the cast iron head, and is not more likely to warp. Clai

I have to agree here. Aluminum's heat dissipation qualities are preferred over those of cast iron. You save a significant amount of weight too. Make sure the cooling system is up to the task of the i

I'd think the iron head would keep more heat and more power in the combustion chamber. These days you can do much the same thing with thermal coatings on both the chamber and the pistons. Don't know

Well I've never had a CI head and am not a race car driver or an engineer, but nearly every R16 I've owned has experienced head warpage, and they all had aluminum heads. My first RL411 warped after I

FWIW, I just pulled the CI head off my '66 because I thought a leaky gasket may be to blame for some heating I was getting. WRONG! No leaking after 107k miles without the head ever having been off. W

Aluminum heads warp due to a difference in TCE (thermal coefficient of expansion) between the aluminum head and the CI block. Aluminum expands at about twice the rate as CI. Under normal operating te
