If your plan is to keep the motor between 454 and 466 cubic inches, I would recommend a set of aluminum heads with 270cc or 280cc intake runner volumes such as Trick Flow PowerOval 280, Brodix RR BBO 270........ 300cc's and larger intake runner volume on these relatively small motors will require spinning them to the moon to achieve high velocity in the ports, which will require expensive parts in the valvetrain and the reciprocating assembly if the motor is to perform properly. COMBINATION, COMBINATION, COMBINATION. No part stands alone.
