Such as oil fed tensioners and engine head studs all for reliability.j

Steel head studs are perfectly fine (and sometimes preferred) for a stock or modified motor. Some of the aftermarket head studs are only for aluminum cases since they use much higher torque specs.
Porsche didn’t always get it right the first time around and changes like tensioners are a worthwhile upgrade. You won’t go to Porsche hell if you use them on a stock engine.

I have an engine builder on staff who knows details better than I do but my opinion is that if your head studs are in great shape without any corrosion, reuse them. If they have rust, corrosion, pitting, etc, replace them with steel studs. If you need to replace them, hit the area around the stud and inside the cylinder register with heat from a torch for a minute or two per stud. It releases the locktite and is much easier on the mag threads than just twisting them out cold. Then use a thread chaser -not a tap- to clean the threads. A chase cleans, a tap removes metal.
