Head compatibility, Will this fit?

http://cgi.ebay.com/ebaymotors/1970...ewItemQQcategoryZ26455QQitemZ4560317021QQrdZ1 <br />its a 1970 60hp head 3cyl<br /><br /><br />Im looking for a head to swap my big 1984 65 hp comm head with.. the 65hp head is thick and has a huge combustion chamber.. im looking to swap it for a head that has a signifcanly smaller combustion chamber so i can raise the compression.. which results in more power!<br /><br />They both take the same head gasket, but i think the water jackets are much different.. do you guys think this head will bolt up?? do you think it will result in a power loss because im going from 65hp to 60hp head.. <br /><br />Thanks / team_starcraft

You may raise compression with this head,and if the gasket is the same,it should bolt on.<br />But between 60 hp and 65 hp I don't think you'll see a difference.<br /><br />Also,trying to 'hop up' a 22 year old motor .... Think about it.Everything in it IS 22 years old.<br /><br />DHP

I honestly take that as an advantage.. The older stuff is simpler.. <br /><br />If i can get the compression up to 8.5-1 or more.. it will give me more power..<br /><br />Does anyone know if they make a jet kit for the carbs on evinrude?

Hi Team Starcraft,<br /> I would go with a head from a later 70hp from the late 1970s or early 1980s. Then you won't have to cobble together a mount for the coils. They're out there, and not uncommon. Poke around your local marinas and you'll likely pick up a good used one. Check if for warping before installing. ..<br />- Scott

Hi TeamStarcraft,<br /> Drop me a line - I found a cylinder head for your motor...<br />Scott (csr112-n@prodigy.net)
