I have been using normal HC gaskets with a 9E1 head and also with a Supalloy head on my 1936 Nippy. I did notice that the gasket did not ft either head perfectly, did not match the shape of the combustion chamber in the head. Somehow that doesn't seem right.
The HC Ricardo head gasket from Dave Cochrane has the same shape as the LC gasket and is not quite right either.
If a batch of "proper" Nippy/Speedy gaskets for 9E1 heads were to be made I would join in.
Back in the 1970's I used a LC gasket made of some dark grey material together with the Supalloy head. It was the only head gasket ever to have blown. I still have one but will probably never use it.
