Well I guess there isn't anything wrong with upgrading the springs and retainers to be safe.Maybe if they went with stage 3 or 4 then they would of had to change those 2 things right away.

the upgrade is more about longevity then mere power. sustained high revs over long periods will have an effect.
stage 1 cams are good to 6.8k stage 2 is good up to 7.5k.

hes still going to gain some power from the cams anyways,not saying it will be a 100hp gain,but someone here in Illinois actually redid the cobalt's 2.2 motor and its a 2.6 now.

The zip tie idea is brilliant, That could be why almost EVERY time we need to hold the timing chain at work, on numerous styles of engines, we use them. they are cheap, and easy to use.

Here are the dyno sheets to compare the bolt ons before tune and after. Then went i get the car dyno'ed with the cams we can compare. And since everyone wants to see number's heres a start.
This is Bolt ons before tune
Now this is bolt ons with tune (NO CAMS JUST BOLT ONs)
if you look at the second run on the 2nd dyno sheet it looks like i drop hellas it was a different tune

that isn't to bad of a gain there,with the cams you should be up some more with hp and torque.You should get headers next at least,unless I am really blind and you have it listed lol.
