Cast Iron Head gasket recommendation?

[RickMcK]

Hi. This question has probably been answered many times with lots of lively discussion, but I would like to bring it up again.

The situation: I have a 36 FH pickup with cast iron heads. The heads and block seem to be flat, but I am getting water in one cylinder on each bank.

What type of head gasket should I use (type and MFG)?
What type of sealant and application process -- not the torque sequence).
What torque value?
How many times will need to re-torque the heads?

Thanks
