[urq] Antifreeze in oil

[Brandon Rogers]

Speaking of "while you're in there etc etc"...there is a 4kq head for sale
on Marketplace for $30.  ISTR during my 10V head project acouple years back
that a 4kq head could be made to work on an urq just like an MC head
could....just need to weld up a small oil passage IIRC, and of course you
should swap turbo valves, cam, etc over.  It seemed that the 4kq head could
be a good replacement b/c they aren't subjected to the same heat and stress
as the turbo heads.  I had a helluva time finding a head that would pressure
test OK.  One caveat...it would require hydraulic lifters/cam, IIRC.
Anyway...could be of use to someone.  If I still had a 10V I would snatch
this up quick based on my experiences....
