OT - but I need help!

[Estanley]

I have asked these question at the S10V8 board but it is not as fast as this board as far as getting answers.

1. Not S10 related- I've got a set of full lenght headers on my 72' C10 wiil they fit a 78 Camaro?

2. I'm putiing my 350/th350 in an 88 or 89 S10. The S10 has an electric fuel pump and had throttle body injection on the 4.3. The pump is in the tank. I would like to just run the manual pump on my 350 with a Holley 650. How can I get rid of the electric pump? OR What is the best way to regulate the pressure down to 7 or 8 psi and still run the return line that the electric pump needs. I
KNOW ITS OFF TOPIC. Oh yeah, I don't really want to changed the tank.

I'm doing this so I can have something to play with while I finish the frame off on my 72.
