2 CENTS:
MY 351 2 BBL HEADS WERE MACHINED FOR 7/16 BB CHEVY SCREW IN STUDS WITH ROLLER ROCKERS 1.73 RATIO. AND LARGER VALVES, AND ALL THE MACHINING TO MAKE IT FIT A WINDSOR. MY COMPRESSION IS ABOUT 10:7 TO 1 WITH THE DOMED PISTONS. CAM IS COMP CAMS WITH DUAL PATTERN WITH ABOUT .550/.560 LIFT AND 335 DURATION, AND HEAVY SPRINGS. IT HAS NOT BEEN ON THE DYNO BUT I THINK IT WILL COME IN ABOUT 425HP.

I WOULD THINK IF YOU HAD A BIGGER CAM AND USED THE PORT PLATES IT WOULD REALLY IMPROVE YOUR HP AND TORQUE. YOUR COMPRESSION SEEMS A LITTLE LOW, I THINK YOU COULD GAIN SOME SIGNIFICANT HP WITH A COMPRESSION BOOST AND CAM CHANGE. LIKE MENTIONED ABOVE 2BBL HEAD WILL GIVE YOU THE VELOCITY YOU NEED. OR AUSTRALIAN 2BBL EVEN BETTER.

BY THE WAY DO YOU HAVE SCEW IN STUDS? ROLLER ROCKERS?
