Random question.. intake exhaust crossover with headers ?

Basically stock 318 with electronic ign,electric choke, headers, 3.23 gears, auto. Drive mostly april-november, somewhat of a DD on weekends, N.E. Ohio. Just want good dependable operation/ and good MPG (if possible)...by no means a race car !

As long as the heat crossover on the intake manifold isn't plugged, you should be good to go.
