Mad Dog 67-72 Big Block 4x4 headers

[i82much]

I've been looking for a set of full length headers for my 72 K10 that has been converted to a 396 with exhaust manifolds. I've found a few posts by people that have managed to make headers for other applications work, and I'm aware of the shorty and Sanderson options, but I couldn't find a full-length header that was specifically built for 67-72 big block 4x4 conversions.

I contacted Mad Dog since they actually list a header for this specific application on their site and they confirmed that the headers are specifically designed to fit 67-72 big block 4x4s.

Has anyone tried these? I'm surprised I haven't read more about them. Seems like pretty good news for a lot of us!
