    Hi, I'm bolting up my headers to my shiny new aluminum heads. Yikes! astoundingly easy to get a cross-thread disaster! So I look up on summit racing and am astounded at the cost for a stud kit:
    https://www.summitracing.com/parts/arp-100-1412/overview/make/chevrolet -- a bargain at about $50
    Or the low brow Mr Gasket header studs: https://www.summitracing.com/parts/mrg-6312/overview/ for $34. At least its not this kit -- maybe for the builder billing a Silicon Valley billionaire as he builds a $250K pro street? https://www.summitracing.com/parts/arp-400-1400/overview/make/chevrolet ($138) What's the difference? (besides the shiny finish). So I did find these: https://www.summitracing.com/parts/rnb-675-003/overview/ for the bargain amount of $9. Of course I'd need to purchase some hex nuts! Can anyone shed any light on this? My 1971 Camaro Sports Coupe is a driver.

    I had to dent a few tubes to get nuts on with 1 3/4" headers using studs. I'm going back to locking bolts.

    For the record, studs can make it a HUGE PITA to remove headers with the engine in the bay. Think if you have the space to pull the entire header back 1.5-2" on each side

    I use studs on the ends and bolt the rest.

    I'm thinking that with aluminum heads STUDS are the way to go... IF you can easily
    work the headers onto the studs. If using Bolts I would use a torque wrench to tighten
    and some kind of thread locking chemical or mechanical device

    I'd go with a good set of locking bolts and not bother with the studs.

    Dissimilar metal contact plus heat. I would rather have a bolt.
