Hi all.
Converting my TH350 to 4-speed Muncie on my ZZ4 350 motor. I'm currently running Hedman (shorty?) Headers. I will be installing all mechanical linkages and the Z-Bar is hitting the headers. I called Hedman Performance Group and they say, none of their headers will work due to the D ports on the heads. Can anyone recommend a Header type with part number that will install on my ZZ4 motor and clear the Z-Bar and linkages?
Thanks, Paul.

Z-Bar hitting Hedman Headers

 

You might give ARH a call,top shelf stuff and they have a variety of conversion headers available.
I have ARH on my car and the quality is unsurpassed.

Another choice is to use a hydraulic clutch .If all else fails

 

Will do. Thanks for the replies.
