Q: Regarding RA630365 copper exhaust gaskets: Are these used in pairs, where you would stack 2 for each flange, or just one per flange? So on a 4 cylinder engine, would I need 8, or 4 total?
Only one of the RA632837 gaskets are required per cylinder. The RA630365 have a raised bead that can be stacked if desired, but not required
Q: If using 2 gaskets per cylinder, do the raised beads oppose each other or should they interlock?
Make sure cylinder and exhaust stack flanges are flat. Check aircraft maintenance manual for proper installation. In most cases solid gaskets should be installed in pairs with raised beads interlocked and facing away from the cylinder. Also check maintenance manual for exhaust nut torque spec. Re-torque after a hot run.
