Will,

For any much-planed head _or_ fancy cam, you should not rely on markings to
set the valve timing.
 
You had better contact Kent and get a starting-point for the cam setting
(ie. how to set it for top-dead-centre on no.1). Then, you would be advised
to get a degree wheel and a dial gauge, and measure the valve opening (dial
guage on top of no.1 inlet valve spring washer) at 5-degree crankshaft
intervals. Then you need to graph your data, find out at what point on the
crank you reach maximum valve lift, and, if necessary, turn the cam with
respect to the crank by how ever many teeth it takes to get max. lift where
it should be.

However, if you don't get it close before you start measuring, you could
damage valves or pistons, even just by trying to turn the motor over by hand. 

I can recommend a reference, if you need. I can also do the timing
calculations, if you e-mail me your measurements.
