I was reving the same 7.200 and i have broken rocker arms two times. Then, put the limit on 6.900 and i never break again. Also there was an option of "soft limiter" on the AEM ecu.
Hard reving especially at first gear breaks the rockers.
And i think RAS is a must otherwise you will easily throw rocker even at lower rpms only good thing maybe you dont brake it.
