[Mgs] MGA Head Differences

[WSpohn4 at aol.com]

1500/1600 are small valve small combustion chamber heads.  1622/1800  are 
larger valve and chamber. They can be used on the smaller displacement  engines 
but require higher compression pistons or you'll end up with very low  
compression.

I  understand that the heads used on MGA 1500 and 1600 engines are  the
same.  Is there a difference in the head used on a 1959  Magnette?  Also,
can an MGB head be used on a 1500 or 1600 engine as a  bolt-on option?
