You can't tell anything from that due to a) a bad view and b) the hydraulic lifter collapsing. You need to either use measurements and then compare with the springs or use a couple solid lifters in place of the hydraulic lifters, mock up the build, and check it that way.
Why would the lifter be collapsed at idle? I thought I had a pretty decent view of one of them.
I agree it is not a great test but I am not having any issues that would indicate bind. It runs fine aside from the cutout at 6k which is not an issue for me.
The ECM will shut off fuel at ~5200 on OBD1/SBEC. So if in fact you are running OBD1/SBEC there is no way in hell it is spinning 6000 rpm. I have tricked my ECM with several input mods and can see 54-5500 on a typical day. Not that it does any good to spin it that high as it starts to run out of steam around 5200.
You used springs without actually measuring the installed height, seat/open pressure, CB or spring rates ? Not to good of an idea.
Since I am a nice guy I`ll give you a hint. Look at Engle with a part number that starts with a 5.

I though you meant when turning it over by hand. Still I have a hard time believing that you can see the distance between coils through the oil fill hole while the engine is running as well as with the oil in the way.

LOL. I don't think you need to be winding it out to 6k.

You can see there is pretty good space between the coils and the spring is remaining cylindrical.
No, I never would have gone to 6k (if it was 6k) if it were no for the tach being off.
Not sure what new springs would get me at this point since I am happy with how it is running.
The only thing that bothers me now is the air/fuel gauge bouncing all over and going lean on decel. I figure the decel is normal since the manual says the PCM shuts the injectors off. Any pedal at all and it goes back up to where it should be.
I was surprised to see I have ~150 miles on it already just farting around the area.

Sounds like your springs are OK but if you're using the SBEC OBD 1 ECU, the rev limiter will cut in at 5200rpm as John mentioned.
The A/F bouncing all over the place with dancing lights is typical of a narrow band gauge when the AFR is close to stoich (14.7), and is normal when cruising at a steady speed or idling. On decel it should go full lean and at WOT it should go rich.

That is very good to hear, that is exactly what it does.
I do not think the tach reading was very accurate - it was on the wrong setting, it is a cheap tach, and I was busy and could have seen wrong. I don't know how fast I was going to calc backwards from gear ratios.
