Good 10.8 valve springs, the predator 69703 and if the track has a stock cam or if you can run a dyno CL3 it is a good cam in the predator non hemi. Our track only allows the CL2 but that also is a good cam, that is what I run in my non-hemi predator. Stay away from the Hemi if it is a 1/5 mile track. If it is a short track where you want a lot of torque, then the Hemi is good, but it will not turn the RPM that the non hemi will. Valve configuration with the 10.8 springs is not a good combination, learned the hard way.
