Can anyone identify these cylinder heads?

Hey guys I have a question for some of you high performance gearheads. As I've stated in other posts I part out alot of motors and in doing so a while back I bought out the inventory of a small repair shop. I ended up with a set of odd looking dual plug cylinder heads that go to a V6 merc. I've had alot of people ask me who made them and I can't honestly answer that as I've never seen a set quite like this. Maybe you guys can tell me who the manufacturer was as theres no markings of any kind on them but I don't believe they are a 1 off head either. They look to good for someone to have just made one set. Any ideas?

Could be a old set of Montys....Those have to be run with a 1 piece adapter plate as no t-stats, IMO worth their weight in aluminum.

IMO worth their weight in aluminum.

is that the $3/# for new aluminum? or the $0.40/# for scrap?

The $..40 pricing....
