the valve tips got higher and took the slack out of the rockers/lifters enough to start hanging open valves until it wouldnt idle

That's extremely interesting as that is what you tracked it down to being. Is Bob going to put new seats in them or what is the fix?

Im assuming it is due to his room constraints with his TTI kit, plus he already goes 8s with a t4 so why change it unless you have too.

The turbo on the dyno came on around the same as the PT88. Just made alot more power above 5500 on a 370ci LS based motor.

I believe that Chevpower had the same problem. I think it ended up being the seats that moved but I could be wrong. The heads weren't All Pro's though.
