I like to use at least one paper gasket per bank, even with iron heads, and I will have the intake cut so I don't have to butcher a perfectly good intake by filing the bolt holes.
When you were able to get a feeler blade in was this with a gasket or no gasket ... if a gasket which the paper or the valley pan and has the valley pan embossing already been crushed, It's a little confusing?
It's a new valley pan, not crushed. I checked with the feeler gauge with just the intake, no pan or gaskets. If using only one gasket, which side of the valley pan?
