1980 Spitfire Head

[elliottr@rmi.net]

I am considering having the head on my Spitfire milled down to give me a little 
more compression.  It is a stock 80 head so it is currently about 7.5 to 1.  I 
am thinking of taking it to about 9 to 1.  Can anyone tell me how much I would 
need to take off to get it to that compression? 

If I do have it milled down, do I need to get shorter pushrods or is that 
within normal adjustment.

Thanks,

Roger Elliott
