Double threaded bolt for header with spacers

[turbobooster]

Does anyone know where I can find the header bolts that are double sided (metric& standard ) that are for header install and brackets/ accessories?

Are you trying to install aftermarket headers? I just ran into this myself. I recently changed these all over to the thread in the cylinder head. I think they were 3/8-16. I found 1 set screw that was long enough. The others I found fully threaded grade 8 bolts and made my own studs. It didn't take much to open the hole of the alternator and a/c brackets so it would all go together.

McMaster/Carr sells a SAE setup stud. Check your A & B dimensions before ordering if you go that route. As TurboWh1 has done, forgoing the metric end and going all SAE. You may want to go with a Jam Nut on the one end for the ignition module bracket & oil dip tube (assuming you have a Hot Air). I don't think a vendor carries the SAE / Metric Stud, or at least I haven't found one and I have searched high & low for a long time. You may fine some used ones from a TB member, but sounds like you already have used ones.

Yes installing aftermarket headers …., I did see those on eBay they look as good as mine , just wanted new hardware for the new setup and wondering how others were making this work ? Say I go with the stud how do I torque it to spec with out a fixed head? Or am I missing something here?

use 3/8-16 all thread, washer and nut , for headers that dont have spacer on flanges just cut pipe for spacer

Use the double nut method.

Here is what I did... Found ARP for the majority of the studs required. Then made my own where all the accessories/dip stick mount. I torqued everything to 30 ft pounds. Slightly over stock. But I'm using all aftermarket parts here.
