IIRC the patriot gold extreems will work. Hope this helps, Eric L

Any LS dual hyd. roller specfic valve spring kit should work fine. Comp 26921-KIT for example......

Make sure you choose the right spring for that cam. Some cams have some pretty aggressive lobes and will chew threw the wrong spring and cause some major headaches in the future. Get yourself a goooood spring.

I just installed that same basic cam, but on a 113 LSA. It's a Comp 285LRR-HR13. I used the Comp 26926 spring kit. Those are a little stronger than the Patriot Extremes (470 lb vs. 410 lb IIRC). Everything fit together perfect with the motor in the car. Runs great.
