I think there was a somewhat recent article in Hotrodding Magazine about a year ago and it sounded pretty neat. I'm not sure if it was cost effective or not. Thoughts?

Otherwise it's a lot of work , not cheap and in the end you still have a weaker bottom end with a heavier rotating mass . The heads are not bolt on, you have to do a bunch of grinding in the valley and add external oil drain lines.

Someone also said years back the conversion costed 5k or somewhere around there. For that price you might as well cough up the 2500 bones for a repro hemi block so you can just use box stock hemi heads.

I thought it was just an external oil drain line. The way I heard it was they blocked the front drain hole and the rear drain hole you had to add a drain line to go into the block or pan. Really not a big deal to do that.

Front and back of heads to the pan for oil drain back. As said it was the thing to do when Hemi blocks were hard to come by and $$$$

Yes they are pricey but not as pricey as they were when these heads originally came out.

My only concern would be the lack of a good bottom end to go with it. And don't say you won't beat on it.....Hemis rev insanly fast compared to a 440 and are just beast's....But yes, they are expensive, and if Stage V is still making them, its an option if you keep the rev's down.

It went 10.20's thru the mufflers on Hoosier QTP's. He did scatter it one time because the bottom end gave up. Luckily didn't hurt the heads, so he got another block and rebuilt it. It stayed together fine after installing the billet main caps.

Beefiest bottom end of any B/RB block, but still not cross drilled.

The Stage V 440/Hemi could be built for a little bit less than the original hemi, but not a whole lot. I think it was maybe a grand cheaper. However, once you factored in the conversion to the billet caps with the cross bolt modification, the gap narrowed even more. One advantage to the Stage V heads is they flow better than the OEM Hemi head.

I have yet to build it as I am looking for a 1971to 72 400 3614230 thick mains or saddles for strength and thicker cylinders. But I have also considered trading them for a set of Stage 6 Chapmans 285 MW heads with the valves & rockers. If anyone knows of a block or wants to trade for the heads let me know. 6463860-corp_0809_01_z+building_hemi_for_less+engineering_hemi.jpg (177 downloads)

What are you going to do about an intake ?
