These are stamped sheetmetal and youll want two for each cylinder. For best results, use them with the concave sides together with a wee bead of red RTV between them. then another wee bead of red RTV on each outer side of the sandwich, to ensure a very good seal between the head and the manifold.

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: Is ACS pn. 08-05229 used as one per cylinder or two per cylinder?

This is used as one per cylinder.

Q: Can part # 08-05270 (spiral wound exhaust flange gasket) be reused, or does it need to be discarded after each use?

Per Rapco: It is recommended that all exhaust gaskets, flat and spiral wound, are changed each time they are removed. They are designed to crush into place to block high temperature exhaust gases from eroding any uneven mating surfaces. If reused they may not seal properly.

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.

Q: What are the dimensions of the RAPCO COPPER EXHAUST GASKET RA75118?

2.25" od, 1.765" id, .05 thick, 2.5" hole center to hole center.
