Are you really getting 210 PSI?  That is really high for a stock cam and I 
assume stock pistons/head.  

If you are really getting 210 PSI make sure you don't have some mix up of 
pistons/head causing this high compression ratio.

If these parts are original, it is possible the cam timing is off. ( I've 
never checked compression with wrong cam timing) Do you have degree specs for 
valve opening/closing?  If so cam timing can be checked without removing the 
front cover by marking the crank pulley or using a degree wheel.
