Thanks alot Jeff orderd one its on its way just excited to get my car back your right the smart thing to do is to wait and do it right

Another question head bolts wich ones do i use if the block is an L28 F54 and the car is a 240z does it matter are they interchangeable? thanks again Jeff for the help

The head bolts are interchangeable - I just did it to my 240Z a month ago. I put a '78 N47 head and the F.I with the electronic ignition on. I mixed head bolts from each - used the short bolts from near the intake ports as they are always in better condition.

( I made 1 fast revving 2.4L motor ) Love it!
