Do the heads have a provision for MFI? You can also measure the valve size. They could have 39mm, 42mm, or possibly 45mm intake valve size. The 2,2 and later heads all had 46mm intakes and the included angle of the valves is less, which will be a benefit with the larger cylinders.

I have the 2,7 RS P&C set in my SS2,5. Even with cutting the heads and leaving out the base gasket I was only able to get 8.4 to 1 CR. Probably not what you would want.

I am guessing JE has or can easily make 92mm pistons. The thing would be to do the math and figure out what CR you want and from that what compression distance (I think that is what it is called), and the dome volume you need. I am sure this has been done, so it should not be a huge deal to figure it out.
Here is an example.
