Cylinder Head Measurements

Cylinder Head Warp-age:
To check the warp-age of the cylinder head you have to get a straight edge and a feeler gauge and check to see if there is any gaps between the cylinder head and the straight edge at any point.

Valve Stem:
To measure the valve stem, what you do is get a micrometer and check the diameter of the stem at 6 different points (at the top, middle and bottom). You need to do this in two directions to ensure the ovality of the valve stem.

Length of Springs:
For this test, you  measure the size of the spring from top to bottom to get the free length of the spring. They should all be within 1.5mm of each other.

Cam Lobes:
To measure the lift of the cam lobes, you need to first measure from the largest point of the lobe to horizontally across from that point. This will give you value A, next you measure across the circular point of the cam lobe. This will give you value B. To calculate lift, you subtract value B from value A. For example, A (38.07mm) - B (31.06mm) = C (7.01mm).
This needs to be done for both Inlet and Exhaust lobes.

These are my measurements for the Inlet lobes.

These are my measurements for the Exhaust lobes.
