Edelbrock RPM performer heads and Hooker headers .Does clear the spark plugs?

[COKE]

Hi,
I,m planning to mount Edelbrock RPM performer heads on my 440.
I have the hooker super-competition headers and i would like to know if they will clear the spark plugs.
I have read that some brands of headers do not clear the plugs with Edelbrock heads.

Is somone running with this set up?

Thanks for the help.

The Hooker headers are not designed for the angle plugs , you can probably dent the tubes to get clearnce & burn a set of spark plug wires every 100 miles or less but Why ?
just get the TTi headers you will be happy you did in the long run
my friends Charger has hookers & they don`t even clear the steering box or torsion bar with stock heads

the drivers side fits very nicly. the passenger side needs on small ding and it works great.   hoestly the headman headers fit fantastic with the e-heads. you can also get a set of doug thorleys that fit great ( same basicaly shape as the headmans but much better made with nice thick flanges and tubes).  i have personally ran hookers and headmans with my e-heads.   with the hookers on the passenger side you will need 90 degree ends and you will need them to have a smaller boot on them.  ive got alot more than a hiundred miles on mine and about 35 1/4 mile passes so far they have been on the car for 8 mothes with the same plug wires and no problems


   another option if you havent already bought the heads is to get the new mopar e-head. they are selling e-heads with a mopar logo on the front instead of the the edelbrock and they have a softplug in the front. plus they use a partnumber that ends in 452-a .  the only real change with the heads over an e-heads is they use a straight plug just like a stock iron head. im sure youll pay a little more for the headS though

TTI headers if you want to run an angled plug head. But, for those of you with existing headers/exhaust systems there is good news. MP has just released a closed chamber 84cc aluminum head with straight plugs. That means you can use your existing headers and exhaust w/o having to go with TTI....and save yourself some serious dollars. These heads are being cast for Mopar Performance by Edelbrock and look identical in every way except for the strait plugs. These heads also have a MOPAR logo cast into them....no edelbrock stampings.

Here is an e-bay auction with pics. They are a little more expensive than the Edelbrock RPM's but that's just the usual MP markup. Paying a little extra for the heads and not having to buy a set of $800.00 headers might make more sense in the long run. If you want to run an HP manifold....these are the heads to get.

The 17/8 Comps fit better than the 17/8 Supercomps which won't fit at all. The 2in Supercomps are much like the 17/8in Comps in that they can be made to fit with some  work. I'm not sure about the 13/4in Supercomps though....they might or might not fit.

Coke, what size are your supercomps ? What kind of shaper are they in ? Worth keeping or time for an upgade ?


Ron


Ps. good pics Mike (Runner)  That shows where you have to clearance a few of the pipes.

[COKE]

Ron,  now i don,t know what size are my headers.The collector is 3" but i do not remember the size of the tube.
Tomorrow i will measure it and post here.

However even with the the stock heads,the spark plugs have troubles with the hookers.
They fitted fine with the Mopar Performance spark wires,but now i have a set of Taylor and i have to put steel protections on the boots.
The #7 and #6 cilinders  wire boots was  touching with the header.

[firefighter3931]

Coke, the 3in collector means that they're either 13/4 or 17/8 primary tubes. Do the Taylor wires have straight or 90* angle boots ?  You might have to swap out a few boots to gain some extra clearance on #6 & #7.


Ron

[COKE]

Ron, they measure around 48 mm wich is not 17/8 inch, but it´sclose.
The taylor wires have 90 degrees boost except for the  #7 and #3 cilinder,wich have a 60 degrees  (or so) boots.
The plugs wich do not fit "Perfect"to fit are the #7 and the #2(Not the #6)
Here is a a pair of pics:

[firefighter3931]

Dang, those two boots sure look tight. Now i know why i don't like the 17/8in supercomps 

The 17/8in Comps fit much better and are a heavy duty tube header, go figure.  The Doug Thorley headers also fit very well from what i've seen.

Here's a link from a Summit Racing employee talking about (and comparing) header fit on B & E bodies :

Thanks for the link

I always though that  Hooker headers was the best.Until i have had a set.

Few weeks ago the engine started to blow from the driver´s side header,just around the place where the 3# cilinder tube meets the support with the head.
I removed the header(This means to remove,antifreeze,steering links,starter,steering column etc,etc..A nice job  )
And i found this:


It was repaired on a weld workshop and i asked to them to reinforce the  welded area on the other 3 tubes to evit the same trouble on the future.(They made a good job,and charge to me a good money too)

The last day,the passenger´s side header started to blow from the same place of the #8 cilinder tube .

The trouble is that just now i can,t to spend money on a new set of headers.Maybe if i were in USA,but here in Spain they  are a "Bit" more expensive  .
Other trouble is that i,m just have built a custom 2 .5" "X" exhaust and i,m worried about to mount other header and meet that it does not fit with it.

If it were for me,i would throw these headers to the junk ...
All are troubles with them .

ron, are you saying the new mopar head is the same as the rpm heads other then the freeze plug and mopar on the end? is that a bare head for sale on the bay?

[firefighter3931]

Yep, those are Performer RPM heads made by Edelbrock for Mopar Performance. The straight spark plugs and freeze plug along with the Mopar Logo are for the guy who wants to use a "genuine" Mopar head on his car with factory manifolds or conventional headers.    Mp must be throwing in the towel on their stage 6's which are a poor seller due to quality control issues and pricing. That is a fully assembled head, btw.

MP is also having Edelbrock cast a Performer RPM dual plane with the Mopar logo cast on the manifold. Basicly the same identical piece with different markings.

Ron, the head on the link you posted are nude,without valves and springs...
There is an extra money that you have to add...

Yep, i noticed that when the link was originally posted. I'm wondering if that pic is just a generic image of the new head that is stripped down ?

Here are some additional sources for the new Mopar head.....these appear to be assembled.
