Unless you wanted to run totally N/A I don't feel like there's bang for the buck having them cnc'd. I'd think there is that same '40HP' or so just doing a few hours of MW opening to the intake runners and then using a MW intake which would carry power further. It's a strong build for unported stealth heads! Them being small and that you were using low compression for pump, AND in consideration of the valvetrain; I may have missed on the cam by 5HP and for that I'm so sorry . I'd have thought it would have power peaked about 200 higher but not exactly sure where the ICL is at currently. I'd bet moving it would shift peak for sure. I don't recall if you mentioned how much spark adv made the best power? For whatever reason, your builds go relatively unnoticed (and maybe that is your goal) but they are impressive relative to the parts you're using. Again overall GOOD JOB!
