i have done these mods twice to date. to set the stage,i was magnachargers first production ssr install i drove the car to their factory in ventura calf, and they had my car for 11 weeks while they fabracated parts and worked out the bugs in the program,ect. so the starting point for Vin#1422 was stock motor,trans. i also drove this car while i was in cal to hotchkis in sante fe springs where it was 4-coronered weighed and measured for future springs and bars, from there the car was driven to the flowmaster factory for a cat backsystem[their first for a ssr]. so now to your question of cam and heads. i took the car to modern day muscle cars in atlanta, where we made a set of 1/3/4" long tube headers which ended in 3"collectors, highflowcats, into a magnaflow 3"x-pipe into a flowmaster dual 3" in/out muffler into a flowmaster dual 3" exhaust. in atlanta we put on a set of patriot LS6 ported and polished heads and a special grind cam that turned out to be too hot for me.my goal with this car was to be as fast as possible, while being completly streetable. the first dyno#s where 450hp with 565ft lbs of tq.at the rear wheels on a dynolab dyno. it was great except for a couple of things. the idle was crazy, you needed 2 feet on the brake at red lights, we couldn't cool it ,ect. so we pulled that cam and installed a cam that is very similar to a stock ZO6 cam
