WHY?

yep , I'm that guy. I've been switching back and forth between an aluminum tunnel ram and an Edelbrock 7193 intake on my 440 for the last 4 years and not once have I used any gaskets other than the valley pan. I use JB weld gray gasket sealer on the bottom of the pan and block ,all the way around, and then around the ports on the top side and intake. torqued to 40 lbs, never a leak. I've even reused the valley pan a couple times, but every second pull , I get a new one
