I bought a 360 that was mfg before the cutoff on the variator change at the factory and it does not have the stamp on the heads. I am going to change the timing belts and need to know 2 things.
there are 2 part numbers on the old and updated parts. Can you see the part numbers on the parts when installed on the cam?
Since overtorqueing/ shoulder length is the situation that causes a problem, have there been any problems with cars that have say 20K+ miles? If there have been NO problems with the older part number in higher mileage cars, it seems to be better to wait until the variatior fails to work properly to replace them.
