Just ordered a set of Indy Hi-Po Hemi heads for my all aluminum 605...AKA Canfield heads with full port & polish $3400...Should flow 440-480 cfm....I will have them flowed locally so I know what they actually come in at...Indy bought out Canfield when they folded.

My old 426-1 heads with me porting them went from 363 to 400cfm and there was more left in them, but the intake valve was the limiting factor. These new heads will have the 2.40 valves....

Randy; let me know what they actually flow. Are the valve angles stock or have they rotated the valves a bit?Dave

I have heard of issues bolting the eddy heads on and really didn't like the flow numbers I saw.

The Stage V heads I got quotes for were double the price and did flow more, but mine is a street car, and you can go crazy $$$ with a Hemi if your not careful....
