head gasket testing?

[lubbock guy]

anybody out there do the headgasket pressure testing, The test where you put a T off the Degas bottle and run it to a small pressure gauge?
I am thinking about do this test, if the truck passes the test, then i am thinking about doing ARP studs, one at a time. currently my truck is showing no signs of any headgasket issues, no loss of coolant, no puking. truck has 104,000miles.

I put a gauge off my coolant filter. Before my truck was studded it would sit right about 16psi. My truck was NOT puking because I keep my coolant level low in the degas bottle. But it was venting at 16psi like it should. Even with my degas bottle full it would not puke. My hg were not blown bad, but the were leaking around #4 & #6.

i was going to use a long hose and have the gauge in the cab, do some WOT runs, maybe hook up my fifth wheel trailer and run it hard, to see the max pressure.
anybody else?
lots of threads of guys doing them one at a time, Heck even the MAD Scientist did his that way, just want to know if it is worth my time to do the pressure test before?

I thought about it but when I did the Blockcheck test it turned the slightest bit yellowish green so did the gaskets as well even though there was no puking. All in all if the head gaskets fail after atleast the ARP studs are reusable and it's just a loss of time. Your call

It only takes about ten minutes and is really easy. It indicates if you have exhaust gasses leaking into your coolant. With these 6.0 engines head gasket failures very rarely do they leak to the atmosphere almost always leaks coolant into the cylinders and exhaust gasses into the coolant. link below,

When I was looking into buying my truck I got one of the kits at NAPA. It was $40 and worked like a charm.
