aq 125 Volvo Cylinder head issues

[jmdriver]

I have a aq 125 in a Bayliner 1950 Capri. I bought it with a bad exhaust manifold. I replaced the manifold and in doing so I find #4 cylinder in the head is badly corroded .

I see people are using a 'steel ring' to fix this problem. My questions are this:

#1) Any steel ring that will fit or does someone manufacture a ring for this
Problem?

#2) Also could JB weld be used to build up the corroded areas? Or perhaps
JB Weld along with a steel ring. Would a #10 strength washer work?

#3) Would a head off of a volvo car motor work, if I used Marine gaskets?

The boat is up and running right now, and it is a 1985, so I figure that it will last for sometime before it burns through the cylinder wall.

Thanks for your expertise....

I did the JB weld thing and it got me thru the summer. Just had to do it again. I heard about the steel ring but haven't found one yet. I also heard that I could get it heliarc welded. I think my problem was the flapper on the outdrive was gone, so I made a new one out of an old tire. I will see how this fix holds up and go from there. Yes a head of of a 1976 - 1983 Volvo car will work it is a B21 block.
