Manny-You may want to compare the valves allowed with those from the 1.6 CVH motors in 1981 and 1982.

While I am not sure about the diameters, the 1.6 "early year" valve heads were "solid" as opposed to the "hollowed" ones in some of the 1.9(s).

The "holloweds" slightly reduce static compression of the motor.

You will also eventually want to put a Quaife in your gearbox and Lee kauffman is the guy to talk to (he is in York, PA).

Lee and Jon Ricker each run them in their 5-speed Escorts (Lee is in ITC; Jon IT.

Jon hangs around this forum from time to time.

Cheers.
