Info. Required. GEN 3. Cams.

Rebuilding Gen 3. Turbo engine.
Inlet cam lobe height from heel to lobe tip mics up at 41.50 mm.
My genuine Toyota printed workshop manual states that "Standard cam lobe height"
Intake. 42.610 - 42.710 mm. with Minimum of 42.50 mm.
I have measured 4 sets of cams now. Both Gen 2. and Gen 3. All mic up about the same.
None of them measure up as stated in the workshop manual.
They are all in excellent condition with no appreciable wear or deterioration.
They all have the same number cast into them. 88362.
There is a significant difference in the calculated lift between Gen 2. and Gen 3.
Does anyone know if Gen 3. inlet lobe height should be 42.6 - 42.7 mm.???
If anyone can throw some light on this it would be greatly appreciated.
Thanks.
