  IT might be that if you put a 1.5 head on a 1.6 block that the drain 
will fall inline well enough so as not to leak. I was thinking that it 
left a small opening where dirt could get in though.  Whereas if you 
put a 1.6 head on a 1.5 block it seemed like you could see daylight or 
a water hole or something.  Been a LONG time since I tried it but 
that's how I remember it being.  Hyd on a mech block was just loony 
for lining up.
