OK, I started the 351W I rebuilt, sounded great, brought it up to 180 deg ran it about 3-4 more minutes. Shut it down and checked the oil. Milk for Oil, Lots of water in the oil My cohort who has lots of experience thinks probably intake gasket. So I look at the edelbrock website instructions, It calls for no gaskets on the ends of the intake, only RTV. Anybody that can give me tips - I APPRECIATE IT.

No gaskets on the end rails is correct on any SBF. Before you tear it all apart, I would purchase or rent a cooling system pressure tester. Pump up the system to 15-18 lbs and locate the source of the leak by listening for sure.

Well, you will get lots of opinions here. Some guys throw the end gaskets away and use RTV. However, my opinion is, if they aren't needed, why would they sell them? It can be a little tricky intalling them. I applied a very thin coat of gasket adhesive both the gasket and the block. Let them get tacky and then mate. This will keep the gasket from squeezing out when you torque down the intake. After that I used RTV across the top of the gasket making sure to get plenty at the ends of each gasket. I used a bead about the size of a pencil. Any excess that comes out can easily be cleaned up when wet or cut off when dry. I have had NO LEAKS and I have had it done for about a year and a half.

I glue on the gaskets to the heads and install the intake till the glue sets, them take off the intake and install the end gaskets with black silicone at the corners and a thick bead along the top(the bottom of the gasket is sticky) and let it dry for a minute or two tham install the intake and torque it down to 20 lb.(or was it 25. What ever the book says).

Also when you get your intake off, check the alinement between the head and intake surfaces. Mine is a bit wider at the bottom than the top which caused some problems. Also run a flat sanding block over the intake surface to make sure all the high spots are gone; I guarantee there will be some. At this point the intake may be sitting too high with all the bolt pressure on the end gaskets causing a gap between the manifold and head- this happened to me too- so when the end gaskets are removed the intake seats better on the heads. Do not overtorque the intake, my machine shop warned me that overtorquing the intake can push the SBF heads out of alignment, even with the head dowels in place.

Alex is correct, I've installed many intakes with Ultra Black silicone with NO problems.
