Cc'ing a head tools?

Here is how I did mine on the cheap. I bought a cheap 100cc ebay syringe, leveled the heads on my bench, then used a cd with a thin layer of grease around the edge and smashed it down over the chamber then filled the syringe to a even 90 ccs with rubbing alcohol and then squirted the alcohol in the center hole of the cd until it was completely full then subtracted the the remaining from 90. I have some pics somewhere. I'll try and find them
