1919 Model O Engine trouble

I have a crack in the inlet tract on the block of my 1919 model 0 has

anyone any experience of repairing this block?

Can I get gaskets readily for this engine?

I have anoil pump, belt driven from behind the water pump, is this

correct? It appears to feed what visually looks like the plunger pump

as fitted to my 1913 Huson model 37 (Continental engine) but this is

sited below the distributer housing.

Is there available literature for this model.

Lastly on the head / block there are two large water holes which had

been obscured by some illfitting copper plates, my car lived in

Canada could this have beena climatic fix or is there a right or

wrong to their presence?

Any other useful tips whilst rebuiding?
