Hello everybody,

I am rebuilding My cosworth yb 200 engine and i am looking for a MLS Head gasket.
I am Using ductile liners and standard bore Cosworth pistons.
The bore will be 90.82mm But all the head gaskets seem to be for 92.50mm bore.
If You draw This out there will be a space between block and cylinder head around the
Piston that is part of the combustion chamber. I can't imagine this is good.
Is It best to go for a custom made MLX head gasket for 90.82mm bore or am i
overthinking?

Kind regards Manu
