I just got these heads done .New Z28 springs and 'GOOD' valve seals , 3 angle valve job , all new intake valves, shaved only for tru-ness, inlet valve area (just below the valve seat)relieved with CNC machine,Minor inlet stem guide blending. exhaust side has bowl & stem guide blending and short side radius work done. never installed afterwards. fit 87-95 350's. I saw an identical set make 20- 25 HP on Dyno, more HP with chip & typical modifications.plus they are true 'bolt ons' Unlike the vortecs.I have $450 in them plus some of the work I did & core price, but i only want the $475 back out of them.plus shipping. The man who helped me with these works hand-in-hand with GM on engine development. , thanx , DAVE
