Post away! I pretty much did all my talk'n in the video, lol. I'll lay a flat edge on the bottom of the head, but other than that, nope. Virtually, this is how I've checked my valve guides and valves over a lot of years. No issues to date.
Same here, valve wiggle and a nice drop and bounce. Fluid check etc and run em. I just want to see if the guides and valves are really all over the place like some have mentioned. Mostly proving that all is bullshit, but if they are I'll post it.
