ProMaxx and IMM aluminum small block LA heads

If your 340 is mild, our import heads work really well. We sell them ready to bolt on.
Good Afternoon Brian, thanks for the feedback. I had planned on roughly 10.0-10.5:1 static compression, RPM air gap intake, this howards cam Hydraulic Flat Tappet Camshaft & Lifter Kit; 1964 - 2003 Chrysler 273, 340, 360 2600 to 6200 Howards Cams CL710581-10 | Howards Cams, 1.5 ratio roller rockers, and a carb in the 750-800 CFM range. Will this camshaft's lift make the best of what your heads have to flow? I thought something between 500-.550 lift would be best for air flow in a street head but don't know the flow numbers on your heads so I wanted to ask your opinion. Should I target a zero deck height with the piston? Are your heads closed chamber?

Thank you.
