Ok, so I'm ready to install my eddy performer intake on my rebuilt truck 360 and there are two types of gaskets for it. One is steel and the other is a composite/paper. I checked to make sure and they both fit, I thought one might be for a magnum. The old ones look like the composite/paper. Also, the block does not have the dowels for the front and rear end gaskets, am I ok to install them or should I make some to keep the gaskets in place?
