The heads look identical. Reading the Bently text. The loss of compression is definately due to piston to cylander clearance which is much greater in the turbo also the turbo has a deeper stroke, both of these thing create a lower compression. I can find nothing in the heads that would alter compression. . both are low compression engines. The manual shows no difference in the heads as far as specs go. but the oil ports are mainly what worries me the most. it seems that the heads have a real tight lubrication system that has to line up perfect.
