Cast vs. Aluminum heads and bang for buck..

j par said

And again it's like I was telling valve flyer, 820 totally loaded aluminum heads compared to buying and spending that that same amount on Factory cast iron.
This is definitely under $1, 000 territory. When you start talkin anyting else it doubles the 820 and then starts tripling and quadrupling...
This isn't Max effort this is bang for buck in the budget realm which I consider and it's definitely my opinion on this one is in the Thousand or less range..

I asked because there is more to cylinder head selection than materiel. Personally, I'm not a fan of many closed chambered heads, especially the stuff Chrylser used. If my choice is an iron head with a chamber I like or an aluminum head with a chamber I don't like, I'm taking the iron head every time, even though I hate grinding iron.

I say that again because just using air flow off of a bench to determine how much power a given head will make is sketchy at best. I've seen heads that flowed like crazy, but didn't even make 1.7 HP/CFM and I've seen heads that didn't flow very well that made 2.3 HP/CFM.
