915's are good for about 600 lift or under. step above Z06 imo. the 918's i believe are for 600 for sure. i have the 918's.

I have the 915's and will be taking them off to put in some 918's .
Also may have some chromoly 7.4 Comp Magnum push rods.
might have to go to a longer rod.

Thats a good cam choice...You'll want 918s due to the higher spring rate. Its going to be a little thumper
