Using secret cams and increasing compression ratio should you want to use oversized valves instead of stock size in a 96-98 ld9 head. Im wondering what the redline will raise the motor to with the 1mm oversized valves and how it effects the Velocity of the head. How will the motor differ from stock valves to the 1mm oversized with port matched manifolds and which throttle size tu use stock or use quad 4?
