LeoneTurbo Posted July 21, 2010 Share Posted July 21, 2010 You could if you used the headgaskets for the DOHC block but since the SOHC heads are different (more combustion chamber volume) you would lose some compression. Personally I wouldn't use any EJ25DOHC block w/o full history as they often need the bottom end rebuilt. Besides that, before you put on the heads it would be best to resurface the mating surface of the block as that is were the head gaskets issues come from - the block deck wears out against the gasket, the heads are rarely warped.
