Sorry to hijack but since were on the discussion of headgaskets to use with different block/heads. I am doing an ej25d block with ej18 heads from my 93 L. I was told that it will be a bolt on affair also. But I am curious as to what headgaskets to use? I think ej257 gaskets would be best. But I also want to raise the compression as this will be an all motor build. Cometic? Help me please.
