My Edelbrock model sensor is mounted on the upper horizontal section of the
exhaust pipe on the right side. Easy to get at and not in the way of anything.
Don't have headers, but it doesn't matter. Being close to the exhaust valve is
not critical, in fact, you want to be after the 'merge' so you collect the
average
data of the whole side. The other side is running the same, unless you have
sideways, asymmetrically jetted carbs.
You can't get too far away, though, because it does have to come up to operating
temperature to sense correctly. Mine seems about right.
