I used stainless nuts/lock washers/washers on my coupe; I would not
recommend this - it works ok, but I do not believe the temper of the S/S
will hold up (on the lock washer) at those temperatures.  On Brendans
engine we used the OEM parts, I liked them.

both cars are n/a, neither car is leaking, but I would tend to
recommend/use in the future the OEM stuff.
