heard a little noise yesterday after i adjusted my timeing down a bit yesterday, so i decided that id check my valves to day, but it didnt sound like that side of the engine, not that i can hear to well. the other head really didnt look to have and shimmer to it, but it only had a few drips of oil to tell by. the intake valve on cyl 2 is adjusted out farter than the rest, but its been that way for a while. as for the magnet test... i used a wand magnet... all i had around, but it did pick up a few bits here and there. i think alot of the shimmer stayed on the head cover when i pored it into a jar....
