I have a 400 that i have rebuilt. I'm trying to figure out the intake gasket though. I went to two different places and the kit only came with the galley pan and the gaskets for the front and back of the intake. I bought a kit off of summit which came with the front and back gaskets along with the sides on the heads. I'm wondering if i need those since i have the galley pan and the kit i was gonna get from the part stores only had the front and back gaskets?

 

Three parts used, front and back valley seals and the metal tin valley pan. Another Ford better idea that sucked. They typically sucked air causing intake leaks. An easy and cheap repair but still, a bad design.
