Anyone with feedback on the Manzo shortie headers?

Those have been around awhile, by different names. Mostly used in street rod apps. I had a set 5 or so years ago. They do not fit cars. They have the potential to fit trucks by the looks of them, but that is just a guess.

Unless you flip them over and mount turbos on top.

They do not fit upside down for use as a turbo header. They hug the block very well, when flipped they hit the heads/ valve covers hard.

Aside from that they are a very well built header. Thick flanges, large collector, tubes were 1 3/4" IIRC.
