Just check your studs then compare them with what SBP sells. Whatever the thread pitch is in your engine case must match what you plan to replace them with. As for the top end, it doesn't make much difference if you replace the acorn nuts with hex. Simply match the threads. I hope this answeres your question.Tom,
Are you saying the replacement head studs from SBP will not work because their threads are the same on each end? Where are upgraded studs with different threaded ends to be found? ~Bikeme
I'm torqueing to 12.5 Ft Lbs, some will say as much as 18 Ft Lbs but to each his own. I think 15 Ft Lbs should be max.Good advice. Thanks DaveC. What did you torque studs to?
it's not the studs themselves i'm sending him there for, simply for a sizing chart so he can accurately purchase the upgraded stud kit made for his motor. millimeters can be a bit hard to measure with out good equipment, better off to use someone else's good equipment then to purchase something that looks right but you're not 100% positive about.Good luck finding a 8mm X 1 bolt or threaded rod at Home Depot. You'll find that 8mm bolts or threaded rod will come in a 1.25 thread pitch. If your engine case takes a 1 thread pitch..."you're gonna need a bigger boat".

I see what you're saying and agree. Using the proper tools to measure the diameter/threads is a good idea. Simply comparing them side to side is also a way to determine what they have. Like SAE fasteners, the difference between fine and course threads are readily apparent when viewed next to each other. Also a tool to determine diameter would be beneficial if the person doesn't have access to a a caliper or diameter guage.it's not the studs themselves i'm sending him there for, simply for a sizing chart so he can accurately purchase the upgraded stud kit made for his motor. millimeters can be a bit hard to measure with out good equipment, better off to use someone else's good equipment then to purchase something that looks right but you're not 100% positive about.
