Not much of an apology when you still keep promoting wrong information Dude. How many times do i need to post a link to the factory ground strap ,before you finally give up with your misinformation.
Check the back of your drivers side head,you'll find a ground strap,if your truck is a 15 or newer the ground strap will be part of the wire harness,prior to that it was a totally seperate ground strap that connected both heads together,then grounded to either the firewall or to the heat shield under the cab aka "The Body"
Give it up ,and admit you're wrong for a change
I am not your friend and your use of Dude towards me is derogatory.
I believe the ground straps you refer to are bonding straps not technically grounds straps and the ground strap on the 2012 had
three ( one with a clip ) where my truck only uses
two that are daisy chained to each cylinder head and then the transmission.
A dedicated ground strap (personal definition) are major grounding points from the battery to the cylinder block or from the cylinder block to the frame the starter or vise versa. I think the factory supplied are referred to as 4F and 6F in wire size
Since the OP stated they placed a ground strap from the cylinder head to the body of the vehicle I advised against it.
Because
Additional electrical current allowed to flow through the cylinder head decreases its electrical resistance and increases the electrical flow.
This provides greater opportunity for electricity to use the cylinder head as an anode if the cooling system is negligible in pH or a dedicated ground strap is compromised and added current is then transferred to the smaller conductor and compromises each ground in succession to their gauge size and location based on they shortest path to ground.
Where older vehicles that use manual choke cables you might find after time they have lost their ability to move the throttle because they have become that shortest path to ground because a primary ground strap was not working because of corrosion or was missing altogether.
Advising against the extra grounding point is like a friend advising someone who talks about starting an exercise regimen to quit smoking.
In my personal experience (before I was formally educated) I attached an insulated wire with eyelets and fasteners to the body (firewall) from my aluminum cylinder head… when it came time to have a valve job the machinist pointed out the needed to replace the cylinder head since the water passages had severe gaps and corrosion.
