Convert to vented Opti?
IIRC, you can get an MSD vented cap w/ rotor for a non vented spline drive Opti. That way you don't have to change timing covers. Although since you're in it already, it's not hard to change. Just remember to make sure the dowel pin on the cam is at the length needed for whatever opti you use, it's different between vented and non vented. Also make sure you have the correct vaccuum lines with check valves installed for the vented version.
