Bondavi,
I do not think those will fit the 380. The 380/420 engine used different manifolds than the 500/560. 380-420 swap, 500-560 swap, but not between the 116 and the 117 engines.
What year and model were these taken from? USA or EU car? Part numbers would also be helpful. Any cracks present? Also, what is your local pick-up price?
