Got these gaskets today and gaskacinched them to both sides of the valley pan. SO, on the end rails, i know you use RTV on each corner where the block meets the head, BUT, do you also use RTV, the right stuff, etc sealer along the whole rail?
I do yes. On both sides of the pan. My 351M in my Ford truck uses a pan. That's how I did it and it doesn't leak. Don't be conservative with the RTV. You can always wipe excess off, but if you don't use enough, it'll leak.
