Head torque and spark plugs and NZ rally

I can not find torque specs in the mechanical info that I have. What

is the recommended torque for the cylinder head to block nuts?

Which spark plugs should I use for this 1926 Hudson? The ones I took

out are not long enough in thread length. Thanks.



Also, my Father attended that New Zealand car rally as a spectator

(we live in Alberta, Canada) and the photos he brought back are

absolutely fantastic.
