Say you bought some used valves and want to make sure they are straight before install. What do you guys think of doing this:

Try to find a guy that reloads cartridges he use a tool to check the runout of brass cases. Two small veeblocks will also work. A drill has too much wobble. A suby valve can be bent only a small amount and it will seat by bending the stem. It will show good leakdown and compression but will be noisey in the seating sequence and sound like the clearances are wrong. It might be better to just take the valves to a shop and pay them to check them. You can buy the tool but if you aren'y going to be doing this a lot the shop will be the cheapest way. My son's sti had all eight intakes bent and it still ran good with good leakdown and compression. Some were only bent as little as .015 but you could see where they kissed the edges of the eyebrows after close observation. He had a little extra valve train noise at 3500 was the only real symptom.

Nothing wrong with what u r doing, i use a makita cordless drill (flat bottom) so it sits sturdy and put the valve head close to something......anything! When it turns it shows the valve head movement like it's in a lathe.
