(about 1,000 miles on rebuilt motor) Do I need to use sealent on the paper gasket between valley pan and intake?

Chances are you will break the seal between the pan and the heads somewhere causing a vacuum leak. Depending how much sealant is on the pan, you may even end up bending the pan so I would just go ahead and have an extra one on hand just in case. $14 isn't too much to spend so you don't have to pull the intake twice to get it to seal...ask me how I know. I don't use the paper gaskets at all. I just use the copper RTV on both sides of the pan and call it a day.

I have R&R the intake 2x now and the gaskets stay put stuck to the pan. get the felpro HP valley pan for the B engine with heat block off/4 paper gaskets.
