Where did you get the bolts from?
I've found the quality stretch bolts depends on the manufacturer, not all are created equal.
in my opinion It depends who made them. My worry is that even genuine Land Rover ones may not be made to the same spec as the 30yr + year originals. I've used stretch bolts on other things in the past and you can feel when they start to stretch as they suddenly become easier to turn (and if they were never intended to stretch, that's just before they break). The first time I used the stretch bolts on a V8 head, that didn't happen, I was just hanging on a long bar to manage the second 90 degrees. When the thread is going into the aluminium block, I was concerned I was going to pull the thread out. I would advise against getting the cheap ones as they are made of chocolate and will snap off half the time or stretch too soon.
Hence my recommendation for turners, as they tend to have the good stuff
I don't think there is a stud kit for the 200 the upside of studs is the finer thread means there's much more control on the tension and they don't need to be torqued up nearly as tight..
But as said you don't need studs for the 200 just quality stretch bolts, if you were running crazy boost and other performance upgrades then yes I'd stud it, but being stock nah!!
Thanks for the detail. The Boost max is at 21PSI, I haven't gone above 18 as I am (was) running it in. Not sure what HP or Torque output I have, it will be more that stock, as it has a VGT, 2.7 bore, gas flowed head, bigger injectors etc. Plus air in and out paraphernalia
