Looks a bit like a REPCO Hi power head that was fitted to the Holden Grey Motor.
The rocker gear looks very similar to the Grey motor rocker gear. But the Repco heads were Cross flow So its not a HI power head.
I will ask around the HTCAV maybe someone knows

Cheers Piquet
The rocker gear is grey motor we think as it does say Holden on rockers and the thermostat housing looks like a grey engine one.

Irving head has round inlet ports & Duggan has rectangle ports.
Not sure, but doesn't the Duggan have the valves staggered?

Thanks Piquet
If you look at this photo you can see a bit of the manifold that came with the engine.
I think cross flow was mentioned but i could be wrong.
Tight fit on the head bolt on the right

Apparently this was made by a man by the name of Chamberland of tractor fame.
According the the elderly gentleman at the museum,to see how much horsepower they could extract out of the red six.
So weather it was copied from an Irving or Duggan i don't know or even what time this is from?
It was made in cast iron.
There was also a four barrel manifold on the floor, it looked like it was set up for a Rochester small primary's and big secondary's
Be it right or wrong that's what i was led to believe ?

Wayne, I think you will find the tractor man is Bob Chamberlain. John Deere owns Chamberlain nowadays
Looks like it was copied from an Irving head.

Also Chamberlain owned the Rolloy Piston Co,that supplied all the pistons to GMH at the time and also some Ford products.
Which adds more weight to what Rodomo is saying ?

With that blanking plate on the back of the head ,could this have been in a boat at some stage.
I'll take a photo to the HTCAV meeting on Wednesday night and if I have time I might drop pats Ian Tates workshop and see if he can cast any ideas for you.
Irvings have thermostat housings on each end- apparently so fords can flip them over and use them- so we end up with a blanking plate on the firewall side on a holden 6.
I wish I never sold my irving... not like they come up very often... now cash has freed up I would love one again.
