Not a fan of using rocker ratios over stock. Duration trumps lift by a bunch and I don't want to load the valvetrain any more than necessary. Here's a build that is similar to yours....

I would have built a little more static compression ratio into your motor. With aluminum heads, up to 10.5:1 works well on pump gas without detonation if you pay attention to the squish (0.035" to 0.045"). Your 11-433-8 cam closes the intake valve at 44 degrees ABDC @0.050" lift, making a dynamic compression ratio of 7.99:1 when calculated with your ~9.5:1 SCR, so the motor wants more static compression ratio to run that cam. 10.5:1 SCR would have made an 8.815:1 DCR, generating considerably more power and still good to go on pump gas.

Run it on your dyno sim and see what it says please techinspector
