damn looks like I'm gonna need to go back in there and check my torque specs... I tightened those things hard and have been driving for a while now on them..

Hey Dark, I have four pieces of advice for you if you want to do the job right:
1) Get a Helms Service Manual
2) Get a torque wrench
3) Get the tool
4) Take your time
Practice makes perfect but make sure you have all the info you need before you start. Sounds to me like you were unprepared the first time you tackled this task. You need to torque the jam-nut down to specs in order to perform a proper valve lashing. BTW, I hope you're performing this task while the engine is bone cold.

The issue is that the nuts are small, so overtightening could easily strip them or snap the stud. Obviously, if you undertighten, the clearance could change (very undersireable).

2. I have the tool
3. I took a lot of time to do it
I've done a lot of work before on cars so its not like I'm tackling this for the first time. I made sure the engine was really cool before I did it. I even did the adjustment at the dealership....The only thing really to be unprepared was I didn't torque them. The times I've done valves before everytime I didn't have the tool and when I had to tighten them wihout the adjustment tool it always moved the adjuster a little tighter than it needed.

(For those of you that don't know... I'm just kidding around. gernby is right, it would be a bad thing if you have randomly, dynamically changing valve clearances).

Actually, If the nuts are loose enough to allow the valve clearance to change, I'm sure the nut will evenually just become a "foreign object" floating around in the engine. The nut and set screw is moving up and down 75 times per second at redline.

I have the Marcucci tool It works like a charm. Though it still took us 4 hours to do as I wanted everything to be absolutely perfect. And I triple checked every gap and torqued nut.
