273 commando Build

I looked the head gasket up in a late 60's parts book. The original 273 part number was #2463338. I checked here on FABO and a thread concerning that head gasket. I see 69 Cuda 440 lists this gasket in his post. Dave's head gaskets are probably a later service part. (the later part number tells us that) I would imagine the "distorted" shape is for larger bores on other engines. Looks like that is where the valves are. The hottest part of the chamber is around the exhaust valve. These gaskets can be used on either cylinder and Mopar's exhaust valves aren't all on the same side of the chamber. Keep the fire ring away from the direct heat.
