My question jerry, is for 72240z.
Soo tell me you slept with your grandma just because you wanted an uncle? Lol
but joking aside i ask, are you a machinest, or have you at least talked to a machinest who says what your stating is correct?
I have built several engines up to and including 1700hp blown aluminum v8's but i havent had The chance to build a L series (but very soon). From my opinion i would say your best to surface The top and bottom of The head and cut The caps as needed and shim. Again this is an opinion we all have them same with you. Now lets try and help!!!
