You need a degree wheel.

Depends on where the engine is. If it's in the car and you can't get your face in front of the motor, go steal your wife/girlfriend's cloth sewing tape measure and measure the circumference of your harmonica balancer as accurately as possible. My sewing tape is marked in millimeters (no, you can't come over and borrow it) -- use that side if it has one (and if you don't have a cloth sewing tape measure lying around, go to a fabric shop and buy one -- they are very handy for working on cars).
Take that length and divide by four. That's how long each quadrant is. Next, wrap the tape back around the harmonic balancer and hold it in place with a piece of tape or something. Rotate the crankshaft one turn marking each quadrant with some of her red nail polish.
That's how I do such things. Except I own all that stuff myself.

The chart I have for setting valves only requires 180 degrees and TDC. I have a degreed wheel but you could just eyeball 180 degrees from TDC and put a mark. My way requires setting certain valves at TDC, rotate 180 and set others, back to TDC and once more to BDC and you are done.

I'm surprised you weren't more upset by the use of sewing supplies and nail polish.

valves are set w/ the lifter on the base circle, just watch the rockers and you will easily see which ones are open and that means the other is on the heel (or base circle). It doesn't take very accurate degree measurements to do it.
