Split the case

Tomorrow the engine will be pulled out to put new cylinders and pistons. The 1300
DP heads, will be machined to fit the 1600 Pistons and cylinders. The thermostat
of the cooling system will be put again.
Probably I will replace the 31Pict-3 for the 34 Pict-3 and also the manifold. The
1300 manifold has a hole on the pre-heater pipe that must be fixed if I keep the
31 Pict-3.
The heat exchanger has a hole on the connection the exhauster that must be fixed
The Crankshaft oil seal has to be replaced because is leaking.

My questions a

If the main bearings are ok and I hope so, do you think that it would intelligent
to split the case only to see if the camshaft and the tappets are ok?

How much time would an expert take, to split and join the case?
