Message: [QUOTE="kleake, post: 1399577, member: 25987"] That is one I found when I was searching as well. You are correct when making that statement although, what I am after is to find out if these are 100% stock tip height valves that never had anything taken off of them. If they are, then the issue is that they never removed any material to compensate for what they took off the heads. OR if I know the tolerances, then I should be able to at least tell what is going on. For example, if there is a range of .050 that the lifter can adjust for, but they only took off .005 from the heads, then there shouldn't be an issue. BUT, if the valve stem height should be say 2.0 inches, and it is 2.060, then I am .060 too tall and it's beyond what the lifter can accept. If this is the case, that means they ground the valves too deep into the heads. If these valves come out right where they should be, then it would point more towards the rockers. I guess at this point i'm kinda digging to try and find a way to determine which component is at fault so I know if I need to simply machine my bridges to make up the difference, or if I need to go back to Ford for a new set of rockers.
