As you can tell by the first 2 replys which were obviously joking around, with the little amount of info given on your combo there's really no answer.

All stock but crank has been turned and balanced,I would like to think the comp ratio is around9:5:1. Any honest answers would be great.

There is no way anyone can guess with any accuracy, you are not supplying enough information.

What heads?(casting number) What CC's are the cambers? What type of valve job?
What short block?
Why do you think its 9.5:1
Whats the durration of the cam
What head gaskets are you using?
Whats the piston to block surface at TDC?
Diameter and length of headers?
Rocker ratio.
Was the cam degreed during installation, how is it installed?(straight up, advanced, retarded?)
What type of ignition, whats the timing?
