AFR heads have weak valve springs from the factory. Thats why they recommend a cam with lifts below .500, like the e-303 with its .498.

I would recommend a comp. cam. Look through thier web page and get something around 215/220 duration @ .050 and .530 lift.

And upgrade those valve springs. You can order better springs from AFR also as an option.
