I REMEMBER DURING YOUR 454 BUILD UP THAT YOU WERE GOING TO GET THE LARGER SIZE VALVES PUT INTO THE LARGE OVAL PORT HEADS YOU HAD PICKED OUT. I AM CURIOUS AS TO HOW THAT WORKED OUT AND WOULD YOU DO IT AGAIN. NOT SURE IF YOURS WERE CLOSED OR OPEN CHAMBERS?
THE REASON I ASK IS THAT I HAVE THE OPPORTUNITY TO HAVE THAT DONE ON THE OLD '063 CLOSED CHAMBER OVAL PORTS ON MY 427. HEAD GRINDER HERE STATES THAT THE CC'S WILL PROBABLY BE ACTUALLY LESS WITH THE LARGER VALVES IN THERE. THAT WOULD PUT THEM AROUND 100CC OR SO WHICH WOULD GET ME CLOSE TO 10 TO 1 COMP RATIO WHICH IS JUST A BIT ON THE RAGGED EDGE I WOULD THINK (FOR 92 OCRTANE GAS ANYWAY).
ANYWAY, THAT'S WHY I WAS ASKING.
REGARDS, MARK
