check KMJ performance for 7 qt oil pans. I got one for my 440 from there off ebay and it's a nice pan for the money ($94 and comes with the pickup tube). They have them in gold finish or raw in case you want to paint it.

As far as stock stamped rockers I know some guys that say they are trouble. Personally I ran them on a 440 with the MP .533 cam for 7 years without an issue. (Shifted at 6000, trapped at 6400). They were just one's I grabbed from my dad's stash that he has gathered thru the years, check to make sure they didn't wobble on the shaft and the cup that holds the pushrod isn't "buldge" looking. If it's a street car with low rpm and .525 lift I wouldn't be afraid to use them, but that's just me.
