I don't know if it makes a difference or not, but when I start it up cold, they're quiet, but once it gets to running temperatures they get alot more chattery..
When I am cruising in say 2nd gear and I give it half maybe a little more than half throttle, it will stay there for a second then if I give it more it will realize I'm trying to accelerate if that makes sense.. I never noticed this until today.. This could be either lack of spark or fuel right?

stock lifters 1/4 turn is more than enough. What kind of comp cams lifters are they? IIRC the Comp-R ones need very little preload. I do a dynamic setting with the car running. One rocker at at time.

Stock preload is 1 turn +/- a 1/4 turn. With that said, on my stock replacement lifters from comp I ran about a 1/4 turn. What does your sweep look like on the valve stem? I agree that you need to run your valves again and use the EVOIC method. It's the most fail safe way to do it. Also there is nothing wrong with a mail order tune on a H/C car, you just have to log your car with AutoTap/Datamaster/etc. so you can have the guy make adjustments. I sent my computer back to Ion 2 times and the tune was dead on. I went and had a dyno tune done and didn't gain anything, but driveability improved a little, not enough to justify the $400 tag though.
