I use the copper spray on head gaskets. It 's supposed to be better for 
heat transmittal between the block and the head. It also give you a little 
something extra that helps take care of any minor irregularities with the 
block or the head. Make sure you torque the bolts in the correct order and 
to the correct value. I usually torque the bolts in three steps so that I 
get an even torque on all the bolts. On the first pass torque to about 
half the value, on the second torque to some value just under the required 
torque ( 5-10 ft-lbs less than required), on the third pass torque to the 
required value. 

Before you do anything, use a flat edge to check the block and head for 
any warpage. Place the straight edge in several locations and in multiple 
directions on both. Try to slip a feeler gauge under the straight edge at 
several points each time you put the straight edge against the block or 
head to see if you have any problems to worry about. No amount of sealer 
is going to work if there's too much warpage on either part. There may not 
have been any leakage before you disassembled the engine, but that doesn't 
mean everything is nice and flat. When you relieve the pressure on the 
head by removing the head bolts, it can spring due to built up tensions 
from all the heat that its seen during operation. It's nice if you can get 
your hands on a flatness gauge like the pros use.
