keep in mind i am not much of a mechanic

but once i restored a 69 dodge charger

the person in charge of rebuilding the motor was a GM guy and very young,...

when i got the charger back, i cranked it and
water poured from the exhaust manifold bolts

seems the exhaust manifold bolt(s) on the 383
go into the water jackets,.....

we removed the bolts
dried the block threads and bolt threads and used the high heat Copper RTV silicone sealant.....it has been several years and it is still holding...

for good measure, i also dropped in the stop leak tablets,...
whatever did it, it has worked well...

hope this helps some...
