I don't have a Mk II engine handy to look at but here is what I have
found.
Mk II heads are the C6OE-M casting; this head has an extra lobe of
material at the exhaust ports that could be machined for the air injectors.
The Mk II heads have the lobe but are not machined and these heads would
have press in studs. This is not the same head casting used on the HiPo
engine.
It also seems unlikely Rootes would pay extra for just HiPo heads on
the production Tiger with a 2bbl carb. I would think Rootes could buy the
studs separately and do the machine work themselves but I also suspect that
might only have been done on race engines.
The 1966 HiPo heads were the same as the 1965 model; they have none of the
above extra material at the exhaust ports.

Subject: Re: [Tigers] More cubes for Tiger
I imagine a deal was made sometime in the early sixties based on a
prototype.
The prototype had a 260. Somebody very high up at Ford said 'you can have
7,000 some odd 260s for x dollars/pounds'. If the subject even came up about
the 289 then the person at Ford said well that will be x+ dollars/pounds.
The leader/decision maker at Rootes, who may have driven the prototype and
found the performance adequate, said the 260 will be fine.
Contracts were written and a bunch of 260s were cranked out and put on a
boat.
When the number of cars exceeded the number of engines a phone call was made
to whomever was the sales contact at Ford and more were requested.
Ford said, 'we don't make that anymore. But you can have a derivative that
is better.'
And so goes the story.
I do have one question for you lucky Tiger Mk II owners. Does the 289 in a
Mk II have screw in rocker studs? I had heard this was an upgrade that was
requested due to some unfortunate events surrounding high rpms.
Stuck in the snow in New England with an Old Tiger in the garage.
