Got these for swapping a 6.2 LS into a Mazda B2200. They hug the block well and the casting appears to be good quality. The only item I’ll note is that the drivers side angles almost straight down, where the passenger side angles slightly outward (maybe 3°) or so. That small difference means the passenger side manifold is slightly over the frame. No biggie. Will update review based on the exhaust sealing.

For the price these can't be beat. I would recommend spraying with ceramic spray paint to prevent rust before installing.

Received the product and am satisfied with the overall quality, but some parts are missing. Listing shows two flanges with seals, only receive 1 flange and 1 seal. Will be returning item unless second flange is sent to me.

They fit great on my 6.0 ls swapped crown victoria. I had originally used factory express van manifolds but the driverside was touching the frame rail so i got these. Took 30 minutes to install. The manifold flange comes with rubber o-rings for some reason. Ended up using mls gaskets instead.

Manifolds were nice. Only problem I had is the gaskets they sent with them were totally mangled up so I will have to buy new gaskets. I had them cerakoted black.

Nice tight fit, clears steering shaft with ease. Hardware is all proper size and everything in the pictures where includes. Would definitely buy again. Only down side is they will need to be port matched as the casting on the lower part of the port is well within the exhaust port by 1/4"
