Sealant on block bolts for timing chain cover / water pump

[6s1640]

Hi all,

I did a new timing chain on the 302-4V.  I cleaned up and reinstalling the timing chain cover, and a rebuilt water pump. I forgot to check if any of the holes required sealant that enters the coolant jacket. Do any of the bolts common to the block through the water pump and timing chain cover require sealant?  I checked a bare 289 block I had, all the holes do not pass into the coolant passages. Is that the same with a 1968 302? I know the FE block has two fasteners that require sealant. Thanks for your help.
