So now I know......

So now I know why they put two front plate gaskets in the gasket set.
Fitted the front plate, then got out the Duplex chain set and found two countersunk screws. What are they for? Ahhh, the crank sprocket fouls the bolts into the bearing cap. These countersunk screws must fit there, but the front plate needs countersinking for them to fit......
Am I missing something here???
Reminded me completely of Cooperman's timing cover story.

Can I jump in here? Make sure you use a proper countersinking tool, not just a bigger twist drill. A twist drill has a different angle of cut and if the screws are not snug into the countersink and come loose the result is not too good!
Use socket head screws as you can't get the phillips head ones tight enough. Also, use 'Loctite' and, maybe 'stake' the bolt heads into the plate by belting a centre-punch into the edge of the c's'k screw where it meets the plate to create a burr which helps hold it in place. From memory the screws are 1/4" unf x 0.5" long.
I hope this is helpful. I'll be doing exactly this later this week when my Metro GT cam finally arives.
