Some plug the hole and some put a 30 lb valve in. I went with the 30 lb valve. From what I've read/heard, the side valve only opens if the filter gets plugged, but I can't swear to that. I change oil/filter every +,- 20 hrs. so makes no difference to me.

As far as exhaust is concerned, see PatriYahts post.... decent exhaust exposes water further back. I came across a used set of KE headers. KE's are the best bang for the buck, if you can find some used, and in good condition. If the ZZ cam is a reversion concern contact rmbuilder/Bob Madara and he can set you up with a good cam. Plus with an rmbuilder cam you'll likely see more tq/hp than with the ZZ cam. But as I mentioned before, I never ingested water into the combustion chamber. At least none that I'm aware of.

There are two bypass. The center one you remove and throw away. The second is closest to the bock, put the 30 lbs bypass in that one. All you have to do to remove them is screw a 3/8 bolt into it and yank them out.

Read this article it probably has the part number in it. I get mine at local chevy dealer for $8.
