173 Steel Head Gasket ????

[Sammy]

Hi Guys,

so im in the process of removing the tired 173 from the bedford, and i've been finding a few things on the holden motor thats not quite what im used to for holden 6 drivelines, most of which is more beefy and i can only assume this is because its more of a work horse than your average holden 6 in a car ....

so last night i removed the head from it and i was quite surprised to find the head gasket is what looks like stainless steel on both sides with some thin gasket in between it .... fire rings look to be similar to any other holden gasket ....

so im just intrigued, is this in fact a factory thing or would it be something after market ?

other stuff like this i assume is the larger transmission lines compared to a car with a trimatic and the larger than usual for the era tailshaft and yoke.
