If he does not use the correct method of measurement ( 2 mm of number one intake valve movement ) then he has no accurate basis for choosing how much offset he needs in the key.
Did you call Brian a CRYBABY ?

Why? He says he has 5* elongation as marked on his crankshaft balancer. What ever he changes on the camshaft position will be double on the crank. Installing the 2* offset key will take off 4* at the crank, bringing him to 1* off.

It's a simple concept that people turn crybaby about because they have to *think* about what they need. At least Fastlane gives the correct explanation: " Note: 2 Degrees
Offset Woodruff Key 0.7mm = 4 deg. at crank"

Yes, the logic is clear.

However, it's confusing to many people. The FSM references everything relative to crank angle. The key that you refer to is listed as a 4 degree key. Fastlane doesn't need to make reference to the camshaft..........it's simply confuses the issue.
