Is it safe to run all motor ls stage 2 cams on built head but a STOCK ls block? Im only looking to put down 300. I hear it makes crazy numbers but i just want to make sure its safe for 10 psi on a t3/t4 50/63 nukin manifold 3 inch dp 3 inch exhaust rc 550s. Its my daily also

 

What brand cams? What lift/duration? What is "stage 2 cams". I would of advised to just get a Vtec head but since your LS is already built then you might as well just use it. Generally, a mild all motor cam works well on boosted applications considering that backpressure is low.
