What exhaust manifolds are these? Gil copy
 

My good friend have these brand new but bought over 10 years ago. I’m thinking of buying them but I’m not sure what they are. Gil tails fit them but they don’t look like any Gils I’ve ever seen and not Hardin Marines copy of Gil either. The castings where the long bolts go looks odd. Any ideas? Of the side it’s written ”power.....”

possible stellings

I would advise against it. Plug access with GILs and their clones is horrible.

Manifolds
 

Are possibly Drakes. They were an early on manifold prior to Gil.

Drakes they are
 

We have a winner, they are Drakes, thanks so much for the help. I’m still curious if they are as good as Gils, they don’t appear to be very common but maybe they were back in the days.

found a picture of Drakes and they look exactly the same.

They didn't have a tendency to crack near as much as the Gil's. I actually had a set years ago and never an issue what so ever. Pressure them and runem.

Performance wise same as Gil's. I can't remember but it almost seems like Gil came from the same mold and as drake. I can't verify that however they are a well built manifold.
