Where can I get extended head studs?
 

I can't find any, only the ARP strengthened ones that aren't longer. My turbo manifold is thicker at the ends, I can only get 4 nuts on = exhaust leaks.

you mean exhaust manifold studs?

Yeah the head to manifold ones

Try Begi?

Have you tried actually calling ARP? They'll do just about anything for you.

Local hardware store???

You might be able to use the longer studs that are used on the MP62 mounting for the HBA (head bracket)....

I'd try calling FM.... or BPR/SoT and see if the lengths work for you.

Dave,

McMaster Carr? They stock a shit ton of threaded products. Not affiliated, just saying.

Thanks for the quick answers, I'm gonna call FM first and then try some of the other places. The local hardware stores here don't stock a whole lot of studs like this so I'd be lucky as hell to find one the length I need with matching thread.

I'm pretty sure the set Miata Roadster sells are a little longer than stock.

I'm going to get the set from miata roadster. They have a stud kit (with nuts and the gasket) for $65 shipped and they will give you the longer studs for the turbo manifold if needed. Thanks guys, problem solved!

Is getting someone to machine down the flange ou tof the question?
