Brent,

If you are using an electric fuel pump I think they should be mounted near the tank as they are more pushers than pullers. I have the Holly blue pump and have used it since 1997 with great results. It puts out over 14 pounds of pressure so I had to use a regulator to get the pressure in the 7-10 pound range.
As for the side pipe holes, I mounted the headers after the engine was all bolted down like it was gong to set and then measyred at least 20 times to be sure I wasn't messing up. Then I had a body man who had a tool he uses for cutting fiberglass vut the hole and I gave myself about 1 1/2 inch clerance all around the tubes. I then used heat resistant tape which matches my color and put a thin strip all around the edge of the exhaust holes after the body was painted. I have never had a heat crack or any other problem.
Oh, and I did run my gas lines so that if the drive shaft or a U joint broke, the shaft couldn't flop around and hit them before I could get stopped. Also used a drive shaft loop to help prevent that.
