W108 Engine # for blown head gasket?

I'm trying to replace a blown head gasket on the m130 in my 280SE but was curious how to know which model to buy based upon engine #? I have the engine number of the block but these are listed as "through engine # 012487" or "through engine # 026281." Any ideas how i know which to purchase? I've been looking at pelicanparts here: 1971 Mercedes-Benz 280SE Base Sedan - Cylinder Head & Valvetrain - Page 1

Thanks

through eng # ----- represents the last 6 numbers in the engine number. There were two combustion chamber designs for that family of engines, the important thing to do above all is set the new one on the old one and compare, the newer one is more closed in shape and if installed on the wrong head you will have a coolant leak into the combustion chamber. I believe the verbiage should be up to and or from.

Thanks all for the replies! Mine is clearly the newer head with the more circular cylinders rather than that with the more squared bottom. It looks like from S320L1999's link that the only difference between these two late-type heads is a difference in the length of the stretcher bolts. Is the width different as well? Or can i buy any of these m130 late gaskets and then just make sure to get the right sized bolts?

For reference, the last six digits of the Engine# are "066360" ??
