WBStore has cnc heads for $999 and good luck doing an ic for less.
Heads headers pulley and tune
Then e85 and roller rocker all with out tearing the engine apart for a cam no ic pump lines and core to deal with not to mention heads will help kr and flow.

Anyone know what a heads header rocker car with gen3 and slicks runs? Iirc someone was in the 12s not sure if e85 or not.
