That's what I was thinking also. I have both ARP bolt and stud kit and for no reason at all I decided to go with the bolts. Is one better then the other? Why? Just curious and maybe I'll swap over to the studs....
The whole argument of studs vs bolts comes down to torsional loading, and bolt stretch.
In super simple terms...When you torque down a bolt, you are twisting the bolt, AND stretching the threads. This adds a margin of error to torque specs.
On a stud...you are only dealing with the stretch, and the rotation of the "bolt" is non existant, since the stud is staying stationary.
this being said...studs can be thought of as "better" but...it's really irrelevant in most instances.
my 7000 RPM, 650 horse, 408, has all studs..and one lonely ARP bolt that (they had to airmail me) under the oil pump. Am i
Thrilled with that?..ehh.. not especially.
Do i think it's the lesser evil than grinding on everything, and running my main cap through a heat cycle to "shave" the landing area...Yes.
To each his own. The typical "do i need a return line?" "edelbrock vs holley" "takeout my thermostat?" style argument.
