Hiya

Does anyone know what the inlet port spacing on a xflow head should be?

Cheers
Gary

It's difficult to measure accurately on the head because of the angle of the ports. I've just measured a standard inlet manifold and it is 99mm - 93mm - 99mm.
Hope this helps.

Thanks David

Use an inlet manifold gasket as a pattern if you are making a manifold, worked for me.
