ZC, milled head, stock gasket. comp. to high?
 

OK, I have a ZC in my 89 CRX DX. the head was milled 15 thousandths, and I have a stock gasket. Is my compression to high to run 8-9psi? I don't plan on going higher, I don't want to build the motor and I don't want to blow it up. I don't know what my compression is, I'd guess over 10 but I'm not sure.

Your comp would be higher...If you have money left try getting a thicker gasket...most of the times the replacement gaskets are thicker than the stock gaskets.
I wouldn't worry too much about it..I would just boost it, but don't boost it too high start at 7 psi if you're using AFC or better...at least with higher comp you'll get a better power range from the start..good for street though.
