Can I get the big block guys with manual transmissions in here please?

[ts71281]

Ok guys, I have a 454 in my 70 c10. I am using the 70 BB engine towers and mounts. Behind the motor I have a 4 speed muncie. For clutch linkage parts I have the proper big block Zbar along with the truck big block style ball stud/bracket setup. The problem is #7 primary on my el cheapo summit headers won't allow me to install the factory big block ball stud setup. What brand headers are you guys running that fit better than these cheap pieces of crap I have on now? I want something that has lots of frame clearance and that doesn't rub on the lower a-frames. Please advise. Pics would be super. I'm not afraid to spend $600 on a nice set of headers if I have to.
