Cost of head gasket

Just changed head gaskets, intake gaskets, front cover gaskets, cht sensor,and the thermostat, for around $260, with me doing the work of course, I reused my head bolts, which you can do, but that is up to you. If I had not been able to do the work myself, it would have cost more than the truck was worth probably. Truck has 212,xxx miles on it and has never run better.
Would have spend an extra 150 -200 and got bolts.

If bolts were meant to be reused they wouldn't come in the ford head gasket change kit for $115 -120 depends on where you buy it but its up to you I only want to do it once so will change mine but lots say they reuse them no thanks I haven't got my gaskets yet just because I can't decide Wats best and I see there's three different lower plenum gaskets and with or without metal bushings I'm using 99 pi intake with 01 4.6 lower on my 97 to keep the tuning valve my pi heads are 01 5.4 heads ,will those be OK for mild 5.4 I know the new 4 layers from ford are best but $100 each not in budget on this n/a motor ,for sure for forced induction

I know they are torque to yield, but they can be reused.

"A torque to yield fastener is mounting hardware which is torqued beyond the state of elasticity and therefore undergoes plastic transformation, causing it to become permanently elongated. Torquing a fastener to yield results in a high preloading of the fastener which, depending on the load frequency and amplitude, can significantly increase the fatigue life of the fastener. When the applied load doesn't surpass the clamping force of the fastener, the strain of the fastener will be lower than when the preloading is smaller than the applied load. It is therefore beneficial in high-frequency high-load situations with a higher risk of fatigue related failure, like a bolted down cylinder head, to use torque to yield bolts.
Compared to normally tightened hardware, a smaller sized TTY bolt/screw may be used while still maintaining the same clamping force. A drawback with TTY hardware is that it normally has to be replaced when loosened, for example when the cylinder head is removed."

I'm guessing you don't know what or where either of them are. Only know them because they were terms said by the mechanic.
