Installed Comp Cams valve springs
 

Over the weekend I got my Comp Cams double valve springs (986-16) retainers, locks, and shims. Let me say it was a pita and it wasn't easy like I thought. My biggest concern is the installed height ! These springs are suppose to be installed at 1.750in and when I was checking the height using the micrometer some heights was not exactly at 1.750...instead I got numbers like 1.745-1.755. My question is can I still use these heads with those installed # being off or should I have the valve seats machined ?
