header pipe to exhaust manifold studs (a WTF question) 200 1988

you are having a problem because volvo threaded the manifold to accept 10mm x 1.5 tpi studs NOT 3/8 x 16


they are very close, the 3/8" bolt is about 0.019" smaller and the pitch's are very close so the 3/8 -16 bolt will thread in the 10mm x 1.5 but the 10 x 1.5 bolt will not fit the 3/8

you mixed them up in the past
