Hello everyone. I am wondering if it is nessessary to do the ARP head studs and new head gaskets if i replace the oil cooler, egr valve, and install the egr cooler delete and coolant filter? I am not really wanting to get to the head studs and head gaskets. The truck runs just fine as it sits but i would like to install the parts mentioned as a preventative maintainese type deal. I want to do the project myself in the drive way but am afraid that if it gets to the head studs that i will have to take the cab off and go through a lot of head ache with that. what are yalls thoughts. By the way my truck it a 2006 f250, 6.0 liter, king ranch. 155,000 miles.
