so yesterday I decide to check my valves, 3 were tight so I go to the local dealer and pick up three smaller shims. I install the shims, numbers up and make sure they are totally seated. Then I throw the buckets over top, and begin with the cam installation. My problem is I'm trying to get the little dots on the cam gears to be as close to flush to the top of the head as I can, once I get the chain in the right place the lobes are facing too far down and making contact with the buckets making it really hard to bolt any thing down. I just don't know what to try next.
