I can't find a head gasket for a Briggs.....

Alright guys,

I officially need some help... I am trying to find one head gasket for one Briggs engine, aka the Gilson's engine.
I took the numbers off the engine today and they are as follows:

Model: 326437
Type: 0135-03
Code: 7401031

It is a 16 hp horizontal shaft Briggs and Larry told me one day that it was the same engine as his Gravely if I remember right.
So can anyone help me find a head gasket?

Thanks,
Casey

Larry came through again and emailed me a manual for the engine as well as a link to the gasket it should be. So after looking it over for a whole 2 minutes I bought the gasket. Thanks again Larry.
