I have to ask again is your engine not freshwater cooled???
As for manifolds if you have a 350 the manifolds should have some brass plugs on the bottom side of the manifolds that you can take out. And the water you used to flush the engine will drain out if they are not brass DO NOT </u> try and free them as you may crack the manifold at that joint if they are brass then warm up the engine give it time to heat up.
Then with the motor off try and tighen it a bit slowly THEN loosen if it doesnt budge forget it its not worth it as manifolds are made out of cast steel and as they get older they get brittle so be very carefull when doing this!!!
I used to have brass plugs on the risers and manifolds and every year I would open them all up and flush out all the crud that builds up and then regreased the plugs again with a good marine grease and was good to go for next year.
Good luck Wolf
