x2 One of the most time consuming task in blueprinting is measuring the roller tip motion over the valve tip (or lash caps).
To properly do it you must measure each cam lobe base. Then with a known pushrod length, check variances to see if you have any of the following:
1. Valve seat ground too deep (or too shallow).
2. Valve tip ground too much (or too little).
This occurs after you have shimmed your springs to the correct height.
The last item I purchase for a build is the pushrods. Dave
