Depending upon the new spring size you may have to machine the iron heads again and/or use spring locators.

A mildly ported 915 head could easily support a moderate street solid roller. We have successfully used .800" lift rollers on 906 heads.

Thanks, I appreciate all of the information I can get. As it looks right now i’ll Have lots of time to research and decide, as going roller on a RB Mopar is quite the expensive endeavor in my world!
