NO-----When I did my cam gears ( my engine is a 90) I noticed the can gear went on past flush. I made an installer spacer that let the gear go until it bottomed. Some where in my posts is how to do a cam gear replacement and it mentions the cam gear going on past flush. Flush will most likely allow the cam to walk back and forth.
Here is part of the post
on my cam the nose of the cam stuck out of the gear about 1/32 of an inch when seated all the way, and there was very little clearence between the thrust plate and the cam gear. It should be .005 or something like that. Using the above method the cam will stop moving when the nose hits the washer. I noticed at this point that the trust plate
had a lot of clearence and I realised that the gear had to keep moving. I made a spacer about 1/4 inch thick to put between the
washer and the gear so the nose would pull through more, the inside diameter of the spacer was larger than the cam nose.
