You need a pretty serious cam change. What you have done is radically altered the intake flow to exhaust flow bias, which is what your cam lobe bias is based on.

My suggestion is to take flow bench numbers and dyno numbers for each head, and your cam card, and email them to Tim Cole at Comp, and have Tim tell you what you need to do.

I do that regularly, as well as sending him results from running lash loops on the dyno.

Then we discuss the next step in cam changes.
