Just dropped a ZZ4 in a '72 short box. I could never get a real bead on headers and fit here in the forum apart from that both Sanderson and Hedman were pretty good. I emailed Sanderson, and they replied within the hour, extremely helpful. Hedman took a week to reply, and not so helpful.
So, for all you guys dropping in a ZZ4, This is what Sanderson has to say:

"The CC3 or CC11 headers would work on your application. Be sure to specify that you have the ZZ4 cylinder heads when you order. D-Port, angle plug Vortec heads require specific dimpling for plug clearance.
In a truck you do not need (or want) too big of a primary tube due to the weight and effective RPM the engine will be spending most of its time. If this was in some Camaro and you were driving it extremely hard, then you could justify a larger header."
Best Regards,
Sanderson Tech Support"
Hope this helps.
A little, sure, but it's not so much for hauling rock as it is for hauling ass.
