I am trying to get a pair of 16 plug hemi heads but need to know more info before i go ahead and buy them. 1.What all do you need to run a 16 plug hemi? (Heads, valve covers, distributor, dual coils, dual ignition boxes, etc.) 2.Are any of these items available to purchase through vendors? 3.Are certain 16 plug heads worth more than others? In addition anything you have on the history of the 16 plug hemis would be great! Thanks, Steve

I cant answer most of your questions, but I do know this, it's not required to ignite gasoline and is only for show....do you have that much cash to spend on show? The parts to make this work are not cheap.
Take care,

Talk to or PM Hemifred. He would know about this stuff and he may even have most of it. There are all different options for the heads, but this of course is not the cheapest venture. Despite making some people on here start screaming, you may want to go with an Indy Legend head kit as they can mill them for the second plugs. It may be easier to put together that way. Another option is the aluminum Direct Connection D-5 heads. They've been out of production for years and are both scarce and expensive to get, not counting the D-5 rocker setup. Like I said, contact Hemifred about it since he probably has the stuff. As for tech info, contact Bob George. He can tell you anything you want....
2.Are any of these items available to purchase through vendors?
3.Are certain 16 plug heads worth more than others?
In addition anything you have on the history of the 16 plug hemis would be great!
Thanks,
Steve

The D5 head approach is a black hole you don't want to get near. It will suck all your cash out of your wallet and you still won't have all the parts needed - special block, heads, intake, headers, rocker arms and stands, etc. Hemi Fred had a pile of this stuff and even he didn't have enough to put one together. I wanted one head for a souvenir, but he wanted to sell all of it. Maybe you meant the D6 heads, which were aluminum, dual plug versions of the D4. The twin distributor drives are hard to get the old ones, but you might be able to adapt one from the alcohol or nitro racers (they use mags). Valve covers, MP used to sell a cast version, but one was for a BAE Fat Head and something was different where it wouldn't fit a standard Hemi head. A coil-on-plug setup would be the cool way to go. I'd suggest sticking with the single plugs though. There are plenty of places to spend money on a Hemi. The SS/AH guys are pushing 1000 HP on single plugs.

I have a set that I never used because the raised exhaust port would require a different set of headers

The 74 Super Stock heads were aluminum, had a Chrysler part number, and they were/are great street heads in the untouched form, and could be made to perform very well when ported.
You'd need dual plug valve covers, two sets of wires, two sets of plugs, and a dual plug distributor.
The nice thing is that for the most part, if you don't like the dual plug setup, you can get plug blockoff's- the kind made for 80's dualplug superbikes work great- and turn your dual plug into single plugs with a change in valve covers, distributor, and wires(ie you eliminate one set).
Dual plugs look cool, but there's not much reason for them beyond that unless you're at the top end of alcohol or supergas performance.
