[Mgs] MGA Head Differences

[WSpohn4 at aol.com]

The head isn't period correct and may not be legal. If you can use larger  
valves you should certainly be able to use any compression pistons you  want.

I  vintage race my 1957 MGA.  A little more compression might be nice,  
and permissible as long as it's period correct.

But mostly,  assembling a back up engine with what I have available is my 
main goal,  and I don't want to give up any power relative to my current  
engine.
