I'm planning to change the valve springs on my 97 SSEi to 105 springs. My thought is if I'm doing that, why not change the rockers at the same time? What rockers can I use? will 1.9 be to much with stock chain, pushrods, and valves? Or should I go with 1.8?

alot of us run 1.9'* with 105'* on a 97, no problems, only benefits

edit: you will also want to change push rods.

Yep, pushrods is another thing I plan to do at the sam etime, failed to mention that. Thanks for reminding me.

The Yella Terra kit that INTENSE sells comes with pushrods and reuseable rocker bolts.

I ran with the 1.9:1

If you use the Intense pushrods, get the oi restricted, I would steer away from lightweight. I had a set of Intense lightweight and one broke.

IMHO, 1:9:1 rockers with Comp cams 105# springs OEM pushrods are just fine. Your not going to see enough HP increase to require a push rod change.
