383 Performer Intake and Valley Pan Install

Ok. "I" would use 3M yellow weatherstrip glue in a "few" places and glue the gaskets to the heads. Next, install the valley pan. Finally lay the second set of gaskets on the valley pan. Now, look about how much space you have between the china walls and the valley pan. Take everything back off and put enough RVT on both sides of the valley pan at the china walls to seal it good (but not be messy) and put it back together and bolt her down. Remember, only 20 LB FT on the intake bolts. If by some chance the intake bolt holes do not line up when you mock it up, you'll need to back up and punt.
