Unstoppable Coolant Leak

Edelbrock 7277

First time I used ACDelco RTV- My favorite hands down, never had any problems ACDelco 88864346
Second time I used black rtv stuff from the autoparts store. I'd have to go dig it up to see what brand.

Both times around coolant ports (only on one side, the other has a ring thing in the gasket), the second time I was extra careful in making sure sealing the valley wall didn't interfere with the coolant port in any way.

Sealant on both the head side and the intake side of the gasket around the ports I assume? I know stupid questions, but we gotta start somewhere. Sounds like you're doin it all right so to "ME" that leaves "something" you ain't found yet such as a craptastically machined intake. At this point, I would be taking it off and literally.......and I mean LITERALLY looking at it with a magnifying glass. You'd be surprised what might jump out at you. From there if you find nothing, it's time to check the intake angle against the angle of the heads. I believe you will find the problem if you do those two things.

Now......one last stupid question. Did you remove the dowel pins from the china walls in the block where the intake ends meet the block?
