Camshaft profile in circle track engines is very crucial to having good acceleration power throughout the entire RPM band. Compression, Camshaft, Cylinder head, intake manifold, and carburetor are all a balance set in order to make your combination work to its very best.
Tell us a little bit more about your current set up, Compression ratio, Heads, Intake, and Carburetor being used. And car weight

Changes I would make, add dome pistons, change to a roller cam, and upgrade to a set of AFR 195 or possible 210 CNC ported cylinder heads.
The Pro Comp heads, flat tappet camshaft, and flat top pistons are holding you back with the no restriction rules.
