After reinstalling the head of my '73 Spit 1500 I found that it was leaking
water out the #4 cylinder sparkplug hole.  I took the head off again and upon
closer examination discovered that there is a small ridge between the water
channel and the cylinder wall, or perhaps I should say there is suppose to be
one.  The block does not appear to be cracked or anything just this small
ridge broken off.  This allows water to enter the #4 cylinder.  Is it possible
to have this welded?  Or is there any kind of RTV that will withstand the
compression and heat?  Or am I in for a new engine block?  With this exception
the block appears to be in good shape.  Help!
