HOW TO SUCCEED YOUR VERY FIRST TIME PORTING HEADS. CAN YOU REALLY PORT YOUR OWN HEADS. WILL YOU RUIN THEM? DON'T BE AFRAID, WITH BASIC TOOLS (FROM A PLACE LIKE SUMMIT RACING) JUST A LITTLE COMMON SENSE AND AND CAN-DO ATTITUDE, YOU WILL REALIZE IMPRESSIVE FLOW GAINS. CHECK OUT THIS VIDEO WHERE I PORTED 3800 SERIES 2 L67 HEADS FOR THE SUPERCHARGED V6. LIKE YOU, I HAD NEVER PORTED A SET OF IRON HEADS, NOR DID I HAVE AND EXPERIENCE WITH THESE 3800 HEADS. BY UNSHROUDING THE VALVES, BLENDING THE BOWLS INTO THE SEATS AND MAKING THE SHORT TURN RADIUS SMOOTH, I WAS ABLE TO GET SOME PRETTY DECENT FLOW GAINS (SPENT LESS THAN 45 MINUTES TOTAL ONE INTAKE, EXHAUST AND CHAMBER).
