Vavle stem height....

How about the varience in the installed spring height? If the exhaust valves are sitting lower (the stem), the spring pressures will be off from intake to exhaust, right? My plan was just to install shims under the intake springs to raise them up and match the spring height of the exhausts. Does that sound right? Right now, there are no shims installed under the springs. In addition, I'll use the adjustment in the rockers to compensate for difference in valve stem height. Will that work?
