I didn't mess with any other changes yet as I knew it would run well enough to check the lifters. The exhaust sounds good too.
On the stock chip that is about all I suspect it will do. Startup and idle well. As soon as you crack the throttle I bet it runs like crap on the stock chip. With Vortec heads I generally have to add ALOT of timing and atleast 50% AE.
