Grrr..

Checked to make sure the block deck was square with a 24" snap on straight edge. Running the straight edge on a diagnal from top of 2 to bottom of 8, it is less than .002" out between the center of the bores (2 to 4 and 4 to 6) but nothing between the lifter to bore area. Front to back is dead on at the bottom of the block, at the bottom of the lifter boxes and at the top of the lifter boxes. It is the same situation with the drivers side but less than .003" between cyl's (1 to 3 and 3 to 5)

Heads were dead on.

Put it back together with new cometic gaskets, hooked the radiator up before installing it in the truck, filled the radiator and pressure tested it again.

The water is weeping from the passenger side inner 3 studs (inside the rocker area between 2 to 4 and 4 to 6).

I pulled those studs and blew the holes out, put thread sealer on the studs and screwed them back in and re-torqued the heads.

Water is still weeping from those inner 3 studs, passenger side only.

Keep in mind LS motors are supposed to be dry head stud bosses.

I have that head off for my machine shop to look it over but I don't see anything wrong with the head.


I am at a loss and could use some thoughts.
