Studs exhaust manifold 3.8

[Ruurd Schut]

Happy to be member of this forum, always helpful once you need information.

the parts book of SNG shows different studs for the exhaust manifolds;
- C11761 13x short studs (early, late 11x)
- C7624 3x long studs (early, late 5x)

The 3.8 engine is ready to be reinstalled, shopping the last items as mounting rubbers etc. but also noticed missing studs in the cylinder head. Checked exhaust manifolds on my current 4.2 engine but see no reason for different studs. I intend to re-use the 4.2 manifolds.

Who can advise me what to do?

Best to look at the jaguar parts catalogue...there is one in the Knowledge base section...best i can see for the 3.8 is that it shows C2525 x15 and C7624 x1 for fixing dipstick bracket....I dont know if the exhaust manifolds were originallt different for 3.8/4.2 cars.....Steve
