Hey Guy's, Is there any valley pan gaskets for 383 with the block offs already on the gasket itself? What I mean is for the 440's it's already blocked off from the stamping process where I have never seen one like this for a 383 other than the seperate plates that come with it. Also do you all use the sealant that comes with it or is there something else better out that you guy's use? I have always used on the ports what comes with the gasket and I will use black rtv sealant on the end rails. I need to pull mine off, I have an issue with a little oil on the #1 plug and I have to rule out the valley pan gasket letting oil get sucked in underneath before I consider it to be something else causing this problem. Thanks Dave,

I'm doing the same thing with my 383 & got the FelPro #1412 valley pan
that has the crossover port blocked off. I'm installing it dry, other that using hi tack gasket glue to stick the 4 gaskets to the top & bottom of the valley pan port holes. Using the Right Stuff to seal the ends of the hold down rails. Had no problems installing it like this two months ago when I changed my heads & cam, but didn't block off the crossover & am now having vapor lock problems due to hot fuel.
