I have the "Hemi tick" only on cold startups for a few seconds.
It used to be worse, I had 2 broken manifold bolts and it ticked all the time. I have since replaced all the exhaust manifold bolts and gaskets, now only ticks on startup.
I use Mobil 1 5w-20 Full Synthetic High Mileage and Mobil 1 Extended Life Oil filter. Both of which I get from Walmart. I'm over 75k miles. I change my oil every 10k miles (mostly highway miles).
Sometimes I tow a 20ft travel trailer. Other times I have payloads up to 2,400 lbs (thanks to AirLift 1000HD, only a 3 inch drop @48psi)
I think on YouTube there is a video of oil filter comparisons. I recall the Mobil 1 oil filters appear identical to K&N oil filters, on the internals. This is a crosscut section of the oil filters, cut with a bandsaw.
m1 filters are blended synthetic media, k&n are paper. You might want to read the oil filter thread in my sig, some good info.
And just yesterday we had another hemi tick at start up killed with redline oil. You might want to try and dump a bottle of lubegard biotech in that m1, see if cold tick goes away. I see you are new to forum, welcome. Here are some threads that would interest your condition, read the ram forum members experiences and see the oils.

Lubegard versus mos2
oil filter thread
The science behind the products is solid, the info continuing to come in is landmark, and the results speak for themselves. These are ram forum exclusives that are backed up by 100's of ram owners over the last decade. trust me you could not build a coalition like this overnight.
First you have to get hemi's that tick, then you have to get ram owners to trust the message, then try the products and review them and contribute to knowledge base. It is not something that could have been done in even one year with the numbers we had here, it is a decades worth of work. Sadly we didnt have the polls up earlier, that is my bad, we lost maybe 1/2 or more of the results. We have been keeping track, redline has been about a 80% success rate generally speaking, lubegard is a newer option for a lubrication strategy and the results are almost as equally promising.
Bottom line, don't think that tick is normal or you cant do anything about it, until at a minimum you dump a 6 dollar bottle of oil soluble ester/moly. good day, Burla
