I am using a Victor gasket set to reassemble my motor.The head gaskets are composition type.Do they go on dry or use a sealant?Should they be retorqued after initial (how many)miles?Do I use factory torque for headbolts or go higher because of composition type gaskets?Thanks!

I think Victor says sealant not needed, but I usually put a little Aviation permatex around the cylinders.  Definately retorque after a few warmups/cooldowns.  Do not overtorque the stock headbolts, you'll stretch them and also stress the threads in the block.
