CAN I RUN FACTORY REC-PORT HEADS ON A SMALL BORE 4.8L/5.3L? CAN I REPLACE THE 706/862 HEADS ON MY 4.8L/5.3L WITH LY6/LS3 HEADS? WILL MY 4.8L/5.3L MAKE MORE POWER WITH HIGH-FLOW, FACTORY REC-PORT HEADS? HOW MUCH POWER ARE REC PORT HEADS WORTH ON A 4.8L/5.3L? WILL THE REC PORT HEADS EVEN FIT ON THE SMALL-BORE MOTORS? CAN YOU NOTCH THE BLOCK TO MAKE THE REC-PORT HEADS FIT? CHECK OUT THIS VIDEO WHERE I DIVE INTO THE INSTALLATION OF A SET OF FACTORY L92 821 HEADS ON A SMALL BORE 4.8L/5.3L? USING THE SECTIONED ALUMINUM BLOCK FOR VISIBILITY, WE CAN CLEARLY SEE THE INTERFERENCE BETWEEN THE BIG-VALVE 821 HEADS AND THE SMALL BORE 5.3L CYLINDERS. CAN WE MAKE THEM WORK?
