Clearwater Magnum Monster Heads?

Most likely it's the junk speedmaster cast iron magnum replacement head.

Have you messed with any of those yet?
Any “ootb” flow numbers?

i'd be really surprised if they had any of the castings that are pictured in their stock. those castings haven't been made for a few years now.

That’s what I was thinking.
I wonder if there are Chinese castings that have the same appearance on the ends as the old EQ heads.

$1300 does seem like a pretty premium price for two iron Chinese heads though.
