240z Header gasket for round port head with SU's ?

[Stanley]

Stock '73 bottom end, 1980 L20aet head (F.I. turbo) with round exhaust ports and F.I. notches. SU carbs from P.O. conversion.

Planning MSA 6-2 header, wondering what header/intake gasket to get. Seems like a common question but couldn't find the right thread. Been running this head for a few years with no problems other than carb/ignition tuning, it all bolted up OK. I can ask the mechanic what gasket he put but he might not remember. MSA catalog says use 77-78 280z headers for round port head. They say call about header gasket if using round port head with SU's but asking here first. Do the injector notches in 77-78 F.I. gasket matter ?  Any other issues ?

Stock Nissan gasket for a 77 - 78 head is good.  Injection notches won't really affect much.  Use Permatex Ultra Copper and lightly coat both sides of Manifold gasket..

Will do.

That's Permatex Ultra Copper RTV...

New gasket even if the one on there looks OK ? Guess I'd buy one in advance anyway in case it gets messed up somehow.

Always new gaskets. Unless you like doing the job twice...
