is there a different style pitman/idler arm I can use to drop the arm and centerlink down so it will clear it is a spool mount kit so im not sure about how I would shim the motor up I need help im enclosing some pictures
I'd say that a '68-'72 centerlink, idler arm and pitman arm would fix your problem. I had 2" cppa headers in my '69 Barracuda years back with a 440 and a spool mount k-frame. I changed '73-up discs but kept the '69 steering linkage and don't remember having any steering linkage to header issues.

great now next question for the pitman arm for a 67 72 setup is that a small sector or a large sector idler arm?
Small sector ,
I have an aftermarket large sector pitman for 67-72 centerlink that i'm not going to be using and I'm pretty sure the right centerlink also.

cool I did not see any replies on bbd I will check again the heated pitman arm works? do you have to do the same to the idler to make it even across the centerlink no crazy alignment issues or funky steering side effects?
Bending the pitman and idler arms will change your toe pattern. How much depends on how much you have to bend it.
Personally I'd look elsewhere for a clearance solution.

Of course if you heat and bend the pitman arm you have to have the front end aligned when done. It would be nice to find a pitman arm that helps but I will be surprised if you find one to take up all of the room you need unless you shim the eng and trans some. But if you do I would recheck your pinion angle. As I said my boys car is a B block and we did not have to move it as much as you do as I heated and tweaked the pitman maybe a 1/4 to 1/2" at the most. My buddy told me its an old hot rodders trick but I know it worked fine for us and has not caused any front end problems as I aligned the front end and everything set to specs other then I put as much positive caster in it as I could.

Ron did you check the toe pattern before and after you bent the pitman & idler arms?
When the centerlink is moved (up OR down) in relation to the lower ball joint arm you have changed the toe pattern regardless if the front end is realigned to correct the toe change.
I suspect you corrected the "toe change" but also changed the "toe pattern" 
I can not say how much bending will actually cause drive ability, handling or tire wear issues, but it does change the toe pattern.

I know how raising and lower the steering linkage can cause the toe to be off when the car raises up and toe out on turns. His did not seem to change much as it was only a little and it has handled the same to us. I remember my brothers tube frame 68 Cuda had problems when he first ran it using a steering rack as his toe was way off when the car lifted and they had to add spacers on the end of the tie rod ends to correct it. You are right about that for sure. But honestly we only had to change his 1/4" or a tiny bit more but definetly not more then a 1/2". Ron

I just didn't want the OP to start bending things willy-nilly 
Someone previous to me had moved somethings around on my Barracuda  and everythime I have to touch the front end I cuss 
It's time for me to re-plot the whole front suspension and get it correct
