My information and experience is that the pistons are different (more compression), and the cams of longer duration, but the same otherwise. I pieced my current 3.8 engine together with a 1984 euro block, one 1982 US head, 1985 euro cams, and 1982 US injection/emissions. All this seems very happy in a 1981 SL.

Everything that went on the block bolted up.

The car is a bit slow to get moving but REALLY starts to pull at about 4000 RPM.
