right so i have 3 seperate instructions about torqueing the cylinder heads and lower intake. but i was doing a dry run today and i noticed my haynes manual says to put RTV sealant around the water jacket ports.

it then says not to put RTV sealant on the head gaskets but the picture shows the block with RTV sealant around the water jacket ports which couldnt be possible unless u put the RTV then the head gasket. so should i put RTV sealant on all water jacket ports, then cylinder head, then lower intake with RTV at mating corners?

Dude, give us more then 5 minutes to answer your questions.

IMO, the water jackets up by the Temp sensor and te one in the back are the weak points on these gaskets since there is not much Surface area there.
That is where these gaskets usually fail. I put RTV around those jackets... I would recommend it.

I've never put anything on the head gaskets other than the spray to make them tacky so they didn't move.

I don't use RTV (right stuff brand) until I get to the lower intake manifold. It goes on the china walls.
