Hello...
I was wondering if anyone has any experience with titanium cylinder head studs. Good idea or bad?
Thank you...

Any for the big-case 6-speed engines will be about 1/2-inch too long. Would be an annoying assembly! But the later-than-Pantah slim versions would be better for a HC engine. MikeV

Actually I was planning on making them. Factory examples are hard to find and like the GM F1 cams there seems to be no info on the WWW, good or bad.

greetings F't9,

choosing 6al-4v for your material?
and
your mating locking material would be . . . . ?

and the torque specs will be adjusted as well . . . . .
(the longer length of this application)
threads are rolled or will you cut?
anti seize component is nickel based & necessary.

i am like you --- a serious love affair with the positive
aspects of this wonderful material.
but i keep the applications & this material choice
in a tightly controlled focus. wheel spindles & nuts
are prob my most risk oriented duty. after that ---
i build to my heart's content!

if your a Ti machinist . . . . .
it's a small world for us geeks.

Hello Archimedes...
I also find titanium fascinating. Carbon fiber and ceramics are also high on the list. I will use 6al-4v with cut threads. OEM steel nuts with anti seize. Still trying to determine a torque figure. Everything on the WWW. is about 50-50 on suitability with most blogs turning into a pissing contest before any real answers are confirmed. My main concern is the weak spot, which is the aluminium threads in the block. I've only made a few parts mainly because I had the material at hand. Axel carriers, nuts and washers as well as some sailboat stuff. If you can share some real life knowledge that would be great.
Best Regards...
