Title: Early A10 engine with later aluminium head either 276 or 376 will not fit into

I have a 1952 A10 basket case which I am restoring. I fitted a later aluminium head/rockers/covers etc instead of the iron head thinking it would be better! Engine fits into the plunger frame but neither a 276 Amal or a 376 will fit. Is there any solution apart from reverting back to the original iron head?
I live on the Prairies of Canada and spring has just sprung after a long, brutal winter and I would love to ride the old Golden Flash this summer!

In what way don't the carbs fit?

It's back to the iron head. The only alloy head which will fit your bike is a twin carb one - rare as hens teeth.
