I have a set of Hedmann headers to install on my 78 4WD with a recently
rebuilt 350. I know that I need to adjust the timing and richen the
fuel/air mixture. I don't know how much adjustment is needed. Can someone
point me in the right direction? The carb is a Holley, not sure of the
specifics.

Thanks
Mark

A good start is no adjustment.

If it was running fine before the change, you do not need to adjust
anything. You should get a little better gas mileage, as your engine is now
breathing better.
