Rumble very interesting article , It puts things in perspective

Your welcome. Thanks to Hughes engines for writing it up. Car Craft also did a bunch of back to back dyno runs between iron and aluminum heads and found no HP difference between the material used for the head. It's about how the head flows.

The use of aluminum allows more compression. So in this, more power should be found. MoPar muscle did a compression test. The ratio was adjusted via head gasket thickness. What they found on there particular combo was that 1 point up in the ratio was approx. 3% more power. More importantly, the ratio must work with the cam being used.

Being that Brain did not get back to use since he was last on (And at the time of this writing, he may be just waking up since I'm in New York and he is in sunny Cali.) I'm taking the liberty to copy and paste a page from his site on head cost. Below is what you'll find on his site.

A few members here have used Brian's services and love his work and the out come of it on there engines. Check out his site.

NEW PRICING...for both the LA and MAGNUM versions will be going up slightly in price come Jan. 2012. New pricing is $1449.00 per set.

To help offset the cost some, we offer our RHS heads in a KIT form including: IMM/RHS heads, arp head bolts, and .030 thick SCE intake gaskets for $1545.00.
