im partial to a set of brodix headhunter 383 non MC that I’m going to try. I bought them last year on a sweetheart deal when someone put a deposit and never picked them up.
Kind of wanted to try a set of SR20 heads but you have to draw a line somewhere. Kind of have to plan your entire build around those heads.

cool stuff. Top notch!!! $$$ but at least your in good hands. keep us informed along the way. If I were to do over I'd go larger ci and eliminate the SC's on 548's. Boat is to heavy for twin 565 NAs. Good luck with everything and let us know any new thoughts after the show.

Be carful might hurt the low-end torque a bunch just saying airspeed will be down at low rpm. What boat you putting them in? My apache suffered planning off with the big heads on it.
