Hello. I have small amounts of oil entering my cooling system. I am guessing I should do head gaskets and get new heads.
There is no smoke and no running issues. It runs great.
I am reading that oil entering the coolant = head gasket failure, and that these heads drop valve seats.
Am I correct?

I will be installing ARP head studs. This vehicle is a DD. Are the ARP overkill with stock power?

believe he is referring to a 4.7 not a 5.2 or 5.9 lastrights. In his signature he has 4.7 so assume it is for this motor

 

Should I update my timing chain?

yes 4.7.

 

do not open the engine up just to replace the timing chain if there is not evidence of a timing problem
