You can't use it the Heads I don't believe EGR/Intake/Exh something wouldn't work that way and the blocks can and may have the same casting numbers but the PISTONS are different the pre 98 has a deeper dish in the top and I know from exp. the 99 pistons will hit a 97 head but not until the engine warms up and get on a pull my idea was to the swap and place a 20 thousanths shim gasket in place cause the motor ran damn good w/ about 180-185 lbs of compression
