Studs are always gonna own bolts. Like when you stud a head on a engine. Bolts only push a object to something, the oject can only go so far before the bolt begins to pull threads. A stud clamps/pulls from both directions, forcing the parts together differently. I always use ARP headstuds on my engine builds when possible. Most ppl are to cheap to payout for a set but I find the worth it, on a car put together for racing where the head will be removed frequently.
Ive decided to source my intake/exhaust studs from honda intake manifolds. They use 3-4 studs dependind on the model, and they are the same thread and metric at that. Im sure i know a model that has some that will work. I had no luck finding any studs at Advance auto or Northern Tool. This engine's fasteners will be bullet-proof when im done.
Planning to look in to this for ideas.
