The original studs were M8X1.25X38 with an unthreaded section in center. One
side of each head had studs and the other bolts. Why? I guess to make head
removal easier by only having to remove on pipe. I like bolts for the ease
of removing heads and I like studs as it is always easier to get the nuts
off studs and not have the bolt heads break off.

Subject: What is the correct stud size?

Hello Volks,

What is the correct stud size for a 1985 WBX? I am affraid that the PO may
have included some exhaust studs that are incorrect in type.

Are the exhaust studs for these engines M8X1.25 and have a non-treaded
portion in the center? Something tells me that is wrong (at least about the
non-treaded center).

All help is appreciated.  I seem to have seen bolts being used to for this
application. IS this correct? Why? is this any better or pratical?

TIA,
Tony
