These custom cut MLS head gaskets are a must for your OM606 stroker build, precision cut bore and coolant passages.
Bore section is opened up to 89.5mm and the coolant ports are opened for optimal coolant flow to the rear cylinders.
I highly suggest you get your mating surfaces resurfaced for a clean and true seal on the head gasket. If your machine shop is capable of measuring Ra values after machining Aluminum heads they are best at 15-30Ra. if you do not resurface your mating surfaces and the gasket does not seal properly I will not reimburse. Pictures of the surfaces will clearly indicate if machining was done.
