G,day<br />I have been looking for a cylinder head for a 70HP Johnson 1977.<br />I have found one head that is very similar, the coil mounts are the same etc. but the profile of the combustion chamber is differant.<br />Most 70HP OMC motors that I have seen have a simple concave shape cast into the head. The head I have here looks more like the swirl chamber that you get on a diesel head.<br />Has anyone seen this before and can I use this head on my motor.<br />Perhaps this head was from their performance motors, the stinger maybee.
