Personally I wouldn't go machining grooves in a perfectly good 1929 block.
I agree with Dave that ventilation might be a good idea, if it's pressurising then an o-ring will not stop oil escaping.
A nice stiff, flat cover and a modern hi-temp sealant (following the instructions!) ought to take care of the rest.
And yes, a flange / seal on the fixing studs so it doesn't come out of the stud holes.
