Type 65 / Nippy Cylinder Head Gasket

I think you're right John, but I understand those for the 65 and Nippy are different to the later h/c gakets. Be interesting to know if anyone has used the 36 to 39 high compression gasket in a 1934 Type 65 without problems. I thought the intrusion of these gaskets into the combustion chamber lead to pre ignition, but I may be making that up?

Coming back to this comment about gasket protrusion into the combustion chamber causing pre-ignition.

It is my understanding the cylinder head temperature during running can reach a maximum of around 400 C at which temperature copper can possibly glow a dull red.

I wouldn't think this could cause pre-ignition, so a miss shaped gasket is not a major problem as long as it seals both water and combustion.

Any comments ?

Cheers, Tony.
