Is there any difference between the '94+ GSR intake/exhaust valves compared to the ITR?
supposedly the cone area is larger, yet is made to be 12% lighter than the stock gsr valves. i believe these are only for the intake valves, though…
Well, going on that info would it really be all that smart to put ITR intake valves in a P72 GSR head?
Yes and No If the Head Is Undamaged and all the valves are great i would not worry about it if there damaged i would consider getting them all replaced at a machine shop along with guides and valve stems i got mine all done local at Heads Up In Auburn Wa Top Notch Work Great Price, There a Guy on Ebay that got all Type R Valves for 170 All 16 that is a great Price… I Bought some from him very happy.
