"Since 1986, people the world over have enjoyed affordable Hemi power thanks to the Stage V wedge-to-Hemi Conversion heads. Based on inexpensive yet extremely rugged 440 wedge block, the Stage V Hemi Conversion motor offers more power than the original 426 Hemi while costing thousands less. A few simple block modifications using common hand tools are all it takes to bolt these high flowing Hemi heads to any wedge block.
Stage V Conversion heads start out as foundry fresh castings which incorporate numerous revisions allowing them to be used on any B or RB wedge block. The stock outward appearance has been preserved for those with an interest in getting the impressive good looks of an actual Hemi. But inside, our Conversion heads feature improved ports which will out flow any similarly prepared 426 Hemi head. It's the best of all worlds original looks, low cost and better performance.

The intake port openings on all Conversion heads are 10% large than stock for enhanced breathing and stock Hemi manifolds bolt right on. The increased intake port dimensions allow the engine builder to enlarge the intake manifold runners to match if maximum output is desired.

All Stage V Conversion heads accept 2.25" intake valves and 1.900" exhaust valves. The smaller exhaust valves are proven to flow more air than the stock 1.94" unit. Also chances of valve-to-valve contact during overlap with radical cams is greatly reduced. Although the head appears to be able to accept dual spark plugs, the repositioned exhaust rocker shaft specific to Conversion heads prevents the use of dual plugs. Besides, unless you are running blown fuel, dual plugs do little more than add to expense and complexity.

Specific Stage V Hemi Conversion rocker arms and stands are required, along with some necessary support items.


SPECIFICATIONS:
Intake Seats: 2.25", Exhaust Seats: 1.900",
Chamber Volume: 168 cc
OPTIONS:
10 bolt intake manifold pattern or stock 16 bolt configuration. Stock low exhaust port or raised port. Stock or aftermarket exhaust manifold/header bolt patterns available.

I alway want to build me a hemi with their kit to put in my superbee but I have sold the bee and never could get the cash for it anyway....

Check out these articles from Hot rod magazine, writer Steve Magnante did it a few years back and shoehorned the motor into his 67 Dart.

Wedge to Hemi Conversion

I thought these conversion heads had basically been shelved by stage v. The way I heard it was there wasn't a huge market for these because of the cost and they were busy enough doing heads for real hemis so these were put on the backburner.

For the extra cost of these heads and their application specific rocker setup would you be any further ahead from buying a repop hemi block?

If I didn't have all the stuff laying around for a hemi that I do, I would build one. My engine builder has built a couple of them, and they were just awesome. Not cheap, but just as fun as a real hemi.

just don't see the point these days. with all the aftermarket hemi stuff out there now just build a real one.

Heard Stage V also has the conversion for the low deck blocks. A 400 block's larger bore, lighter weight & strength would make for a great "Hemi".

Ladies, take a chill pill....

The Stage V website hasn't changed in years, do they even still offer this stuff?

You're right & totally forgot about the intake issue for a B block. I know the 400 is a stronger block than the 440 & weighs less, but w/ all the fabrication & hassle needed to bring it to life, I could probably build an all aluminum Hemi for not a whole lot more. Still would like to see how a low deck hemi would perform.

FWIW you know darn well all he meant by a "real" hemi block was a block designed from the ground up to run the hemi heads, not one that takes modding and pricey conversion heads that are no longer on the market. He never said anything about the earlier/later Hemis, I don't know where you're getting that stuff from, and since they were Hemis from the factory designed to run hemi heads, they are also "real" Hemis FWIW.

Knock it off!

Stage V makes a low deck dual 4 intake to match their heads, if you want a 383/472 or 400/499 or bigger, stroker hemi motor. Here is a pic right from their website.

You could also modify a fuel injection setup from Hilborn to fit the low deck blocks.

The 383 Hemis were the best ones in prostock.."back in the day".
