Recently went to a MII set up and have these manifolds that were in my '54. $60 for the set picked up, shipping would run approx. $15-$20 depending on location. Passenger side a '60s rams horn, drivers side is a early 90's Camaro with all the smog ports capped off with brass fittings.
Bumpity. Forgot to mention, but should be easily viewed in the image, one stud on LH side needs replacing. Also, I'm including a can of Calyx from Eastwood that's still 95% full so you can make these (and any other cast parts) look new again.
