I have a copy of Performance Trends Engine Analyzer Pro v3.9, I'll have a go and run it thru but will need some more specs from you - do you have more detailed specs on cam? Timing card info would be best. 1.5:1 rocker arms? This program relies more on numbers than picking parts out of catalog so I will take my best guess on stuff I'm not familiar with and you can correct me later.
Head data I pulled from Hughes website, using 2.02 Iron Ram specs:
