Since I see that the conversation has moved over here, Hi.
I would not run just one intake per cylinder, as you will have a ton of fuel pool up on the disabled intake valve in the bowl area. It will eventually evaporate, but it will pay hell on warmup enrichment, throttle enrichment, and unstable afrs on cruise. If you regrind the cam (that asymmetric cam I was mentioning early on in the TZX2 thread), it will approximate the collapsed hydraulic lifter shown here with the 4G63 head. Do not cut the tappet, as the excess valve lash will cause the tappet to bounce around, chewing up the head tappet bore, the cam lobe, and possibly mushrooming the hell out of the valve stem. Regrinding the cam for that asymmetric flow will prevent pooling of the fuel behind the valve, as it will still open.
