[Fot] Head Thickness

[damys at charter.net]

So we just got the head back from the sonic test, picture attached.  Our 
numbers are quite a bit less than Chuck's.  Do you guys think we will be 
OK  at .065?  Our compression, according to our calculations, is 9.76:1. 
This seems low to us.  Our combustion chambers are 34.5 cc's.  The total 
thickness of our head is 3.283, and we're bored .010 over.

Does the compression seem right for this thin of a head?  Are we OK with 
only .065" of material to the water jacket?

Thanks,

Dave and Alex
