Change the intake manifold for a L-88 type dual plane, and maybe change the brake booster to OEM. +2 on headers, and an L-88 hood would have been cool too. But I like it.

That intake manifold just screams “oval port”.

No casting mark on the ends of the cylinder heads, so it is indeed oval port.

Rally Green / white is one of my all-time favorite color combinations. Well done!
