    my DD has a .61 lift cam and for sure gets hardened pushrod due to lift and ramp angles on the cam. First time you bend a pushrod you'll kick yourself for not putting the hardened rods in. They are cheap insurance. I don't believe the stock pushrods will be able to handle the spring pressures of the Isky springs.

    I Used The Camaro Heads Because A Buddy Of Mine Had My Machine Shop Build These Heads For Another App. And Walked Away With My Machine Shop Holding The Bag And Being I Had Not Had My Customers Heads Done Yet, I Just Got My Machine Shop Out Of A Bind By Using The Heads He Already Had Built. I Had Another Set Of Heads To Use. Thats The Skinny On That. I Installed The Asa Ls6 Springs Last Night And Man I'm Here To Tell You With The Tune That Was Done Those Big 4 Wheel Drive Tires Boil The Pavement! Thanks For All Ya'lls Help, Hopefully This Info Can Help Someone Else!!!!
