Default Re: Valve timing

Ok
I mapped out the cam this morning
I actually did a graph of the whole cycle.
But these are the figures .taken at .050 lift
inlet opens 14 deg After TDC
inlet closes 32 deg After BDC
inlet max lift .292 in

exhaust opens 32 deg Before BDC
exhaust closes 9 Deg Before TDC
exhaust max lift .302 in

the opening of both valves is very slow until .020 lift then it ramps up quickly.
I mapped the full open and closing of both valves in increments of .020 lift ,except from the first movement of the valve until .020,I did it at .005 increments.
I have the ford service books ,but they dont show what lift the figures are taken at.
I will have a look and see if I can work out what the have used.
SO, should I change the timing to be the same lift at TDC for both valves?
