yes , 2-Step Headers with 2.000" OD and 2.125" OD will still work with your Engine
making its Peak HP at 8500 RPM , and will still be beneficial to 9000 RPM

.... these Specs are for Peak HP occuring at 8500 RPM :
Calculated Exhaust Port Flow @28in.= 280.0000 -to- 299.8402 CFM @ 0.904300 Lift (no Flow Pipe)

Man I appreciate you a whole bunch.

And by the way, I bought a copy of Pipemax a couple of years ago but I've never have been able to get it to work. It was in a bundle on this site.

Reckon you might help me with that?
