Thanks for the reply and the info. They both look like good heads. I spoke with Best Machine about hemi heads and they suggested the Victor because of price and they come with bigger valves, but does bigger valves guarantee more flow in a hemi head? The stage V has a 168cc chamber and the Victor has 170cc chambers. Looks like the stage v head cnc'd flows 407cfm@.700 and the Victor flows 450cfm BM tells me. Its really hard to find much tech like flow numbers and such about the Hemi engine. Surprised there is not more info out there. Must be top secrete.

I built a hemi dart years ago using the hooker 2-1/4 primary tube 4 inch collector original style headers. I did it the factory way. clearances shock tower, moved master cylinder on flex lines, cut down steering column outer tube, spaced K member down, elongated holes on steering box and moved it over, etc. even then i still had to have some header tubes modified to fit.
If i had to do over again I would use a motor plate, and have headers custom built. Put the motor in a place where valve covers come off, might still have to do offset master cylinder and some shock clearance work. But moving steering box and stacking k member, i wouldn't do that ever again. I built the car around the headers, next time build headers around the car.

Thanks for the wealth of info guys, much needed. I'm planning on using the TTI A body hemi header . Tubes are only 1 1/8" thou, so should be a scunch easier to fit. Do you really mean 2 1/8 inch primary pipes?

The Stage V heads that Tim at FHO sells are not stock, he has them CNC first before selling them. I'm not sure what they flow but I do know they will make 800 HP on a 572 C.I. 10.5 to 1 compression pump gas motor at 6500 RPM with a mild street solid roller cam with dual 4150 EFI throttle bodies

I agree Andy. A 572 wedge would be the smarter way if i just wanted to go fast. I want to go fast and look good doing it. You know those big valve covers with plug wires sticking out the top is super sexy. Always wanted to know what makes a Hemi tick and want to learn all i can about them. This will be an expensive project for sure, but will have plenty of money and lots of time once i'm retired. I think i'm gonna pull the trigger on the Bill Mitchell block real soon here. Still undecided on the stage 5 head or the Edelbrock victor JR Hemi head. I'm hearing more good about the Victor head at this point. Very similar to my build.

I was looking over on Scott Browns site and he has the stage 5 replacement heads assembled and complete for about $4700/pr. I honestly don't know what head would be needed on a 572 Hemi with between 11:1 and 12:1 compression to make roughly 900hp street/strip deal. That replacement Stage 5 head it advertised at flowing a tad over 400cfm. I purchased my Stage V heads from Scott Great guy to work with, The only reason i would think about going with FHO is if you wanted to O-ring the heads for the intake, Its a diffrent offset to make up for the gasket, So you cannot just have the Heads from Scott machined to install O-rings, If your not worried about the O-rings and you will be using a standard gasket Scott will set you up with a great set of Heads.
