Yep the head is mated to the block. I was successful in finding coarse
manifold studs and the thermostat studs where ok. I still haven't tried the
plugs. They go in about 5 twists by hand and then stop. At the moment I am
thinking I will put a little more torque on them with a wrench but if they
required too much force I will need another plan. The threads look like
they are fine (not coarse). If anyone comes up with a different idea, give
it to me. I am going to call Northwest Imports as soon as they open this
morning.
Thanks to all the other replies as well.

Umm, I suspect you won't find any fine threads in an aluminum casting...
Don't know why the spark plugs won't fit. A thread gauge would be helpful
here. Am I correct in assuming that the head is already mated to the
block?
