As a second condition to check, see if the cam lobes are centered in the lifter bores. If they are slightly forward too, you know what to do...
I pulled the cam gear and from what I can tell the cam gear is riding on the block like it's supposed to do. But I did find that there is about 1/4" + deflection in the timing chain. So, I'm looking to replace the timing chain and gears. I'm not use to seeing so much deflection, this may fix my issue.
