Cometic 4.250” Big Bore M-8 MLS Head Gaskets
Ohio based manufacturer Cometic now has 4.250” MLS (multi-layer steel) big bore head gaskets for oil cooled M-8 models that do not require the heads to be welded and resurfaced.
“This makes a 4.250” big bore top-end a truly bolt-on kit now,” says Cometic’s Jason Moses. “This is the largest bore you can go to without boring the engine cases. The new design means that the oil hole in the head does not need to be welded, making them a true bolt-on kit.”
They also fit the coolant cooled head with no modifications and are available in all the custom thicknesses in stock bore 3.937” to 4.250”.
