Could I please get advice on how to winterize my 460 jet?  I posted the question on Performance boats also and did get one good reply.  Just getting ideas to make it foolproof.

I purchased a '76 Cee Bee Avenger last Sunday, 460 CI, Berkely pump.  Unfortunately I did not take it to the lake first.  The engine ran fine when I was first looking at it--we did not hook up water to the motor--no smoke at all.  When I brought it home and hooked up the water, it hydrolocked.  I pulled the plugs and got water out of 2 cylinders on one side and one on the other side.  I did not pull it apart yet--I am trying to find if the seller is going to do anything about it.  My first guess is bad heads.  The heads are D3VE-A2As.  I have a chance to buy D2VE's pr D0VE's from a guy on-line.  Any advice on which of these heads is the better ones to use?  I haven't been a Ford guy since the '70s when I was in high school.  Of course I do am not certain what is wrong with the engine until I tear it down a bit.  Hopefully the guy I bought it from will pitch in some money for the repairs.
