    Why did you change to a 1.5 rocker if 1.6's were OK before? Did you adjust the pushrod length when you changed ratio?

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

    I never ran the 1.6's, but that what was origanally on these heads. Pushrod length shouldn't matter. The 1.6 will push the valve open further, or so I'm told. I need to find out if my problem is that my steel roller tipped rockers are evidently for vortec heads.
