Header studs/cap head bolts?

[Robsweetland]

Want to change for stainless cap heads looked under mods but no joy, has anyone got the sizes I would need for an sf mod, stainless washers maybe?

[IanDMacDonald]

Howdy- That's one thing I'd recommend you not to do. Buy new studs, buy the nuts, and enjoy the look.

The po changed to bolts rather than studs, are stainless studds nuts an option?

Those are a 10mm fine thread IIRC, and you won't find anything ready-made in stainless because SS galls so easily in a fine thread. You may be able to find a chrome nut; somewhere on here is a post where the owner found some that would work, but he had to make the washers. The ones he found were not duplicates of OEM, and there was no follow-up to know if they worked out.

If you know a machinist, it wouldn't be too hard to make some out of some stainless hexagonal bar stock. MAKE SURE YOU USE ANTI-SEIZE ON THE THREADS!

Thanks, found on evil bay a full set stainless with nuts wash:-)ers and gaskets made as a direct replacement for 50 GBP

Studs better stabilized cyl. and head.

I put stainless acorn nuts on mine. They got slathered with a generous amount of anti seize compound first. Since the block is aluminum and the studs are steel, there will always be some galvanic corrosion going on. Adding stainless may make it worse, so anti seize is not optional. You have to use it.

Thanks for the info, the stud kit comes with a tube of anti seize

[Robsweetland]

Question, does anti seize make it more likely that nuts will come undone through vibration?

No. Just be advised that if you use a torque wrench, you'll be applying more torque than if the threads were clean and dry. Torque specs are given for clean dry threads unless otherwise specified.

I would use the antiseize. Check the exhaust bolts periodically.

Ok,thanks

Those are nice looking but at $76 dollars. I just went to my local Ace Hardware and found what I needed minus the studs.
