Default exhaust gasket direction/orientation

doing an exhaust swap and in the excitement I didn't pay close attention to the orientation of the gaskets. The flat metal ones have a slight flange around the holes, -does the flange go 'in' to the cyl head, or 'out' into the exhaust header? (see my primitive ascii diagram below)


cyl head
===---------------==---------------===


gasket

----\_________/-----\_________/----


exhaust header

----\ /------\ /----
| | | |


This would be an example of the flange going 'out' from the valves and 'in' to the header. (i think this is how it was, can anyone confirm/deny?)

While I'm at it, I'd like to confirm the orientation of the metal mesh washers too, they're a sort of a 'V', which direction do they point?


like this, or the opposite?

Thanks

and on that second one (the donut washer), where's the best place to slap some goo (high temp silicone or exhaust paste)...in front of it, or behind it, between it and the flange of the pipe?

I don't think the orientation of the metal flange gaskets matters, I've had my exhaust off a couple times and didn't get that concerned about it, and I've had no leaks.

Not sure about the metal mesh V-gaskets, I don't have any of those....

The old ones should be wedged into the midpipes you took off, look at them. I instlled mine so they squashed v pointing down flow btw, thats teh only way I could do it without folding them up all crooked.

I followed my hunch, as 'drawn' up in this thread, and so far, no leaks

Yeah Sorry about not replying DNA I think I understood what you were asking but couldn't figure the ascii pics out so that I could reply in a way that made sense.
