The NA engine does not have the high temp exhaust valves fitted to the turbos. I'm running a Jack Lawrence exhaust header and advanced timing in my '76 EMS with good results.
Are you an auto or 4spd ? A 5-spd also adds some off the line oomph over the 4spd due to its lower 1st gear. [ Assuming 900 4spd is same as '78+ 99 ]
