is it really needed? i just got a used 455 olds dual quad intake. i can not get the bolts in with it on, i took it off and the intake bolted down. i never worked on a olds motor or any other motor other than a chevy, i just dont understand the point of it. if its needed please tell me so, i just cant figure out how to install it without opening up the intake holes to make it work. i also had the valley pan locating bosses lined up to there holes.
It is not really needed. It prevents oil from burning off the underside where the heat risers go through the intake. Cut the center sealing areas out leaving only the water jacket areas and use a Mr. Gasket fiber intake set, throw away the rubber end seals and squirt a good high bead of RTV across both ends. Let it set up some before installing the intake.
I would use one, especially if you don't want to burn oil off the bottom of the intake. You can trim down the sides so it sets into the valley without being a "gasket" between the intake & heads. You can use regular composite intake gaskets that way.
thanks guys. i did install the heat riser blocks while i was there. the funny thing is the eldebrock gaskets doesnt have a hole for the heat risers. but i magin over time it would have burned out anyhow.
No, Olds routinely installed parts that weren't needed, just to increase production costs... I think it's hilarious that the aftermarket routinely tells you to discard the stock tray gasket, use paper gaskets, and instead buy their aftermarket valley baffle. By the way, I installed an old Edelbrock C396 dual quad intake on a 455 Olds with the stock metal intake gasket with no problems. You need to be sure that the raised bosses around the four outer bolt holes on the gasket fit into the recesses in the heads. This is what locates the gasket correctly.
oh a funny guy. ill stop here with this one. if you read my post i said i had them in, not a retard. thanks for your help joe. turkey tray is laying on the floor. motor is running strong. have a good day.
