Stephen,
yes they are loctited, otherwise the spouts go around and end up in a position (at the end of the thread) that does not line up with the position of cups on the drip tray. This is not just for your machine but for almost all on the market.

Hi,
Actually, there is a simple and easy way around this. If you go to Repco or Auto One, eg you can buy a packet of 3/8" Neoprene O Rings for a couple of dollars and put one or two on the PF threaded section before refitting the Spout. All you need to do then is to tighten the spout up against the O Ring(s) until the correct orientation is achieved. Once on, they will not loosen and fall off as the tension against the O Ring(s) keeps them tight.
I used a bit of alfoil in the threads to do the same thing.
As for the weight of the Gaggia PF being upped by the shank, while this may not be as directly coupled to the group thermal inertia as when the brass is around the basket, it is still a heat sink directly connected to the basket region so it does help. That said, it shouldnt make much difference with the std Sylvia PF if you arent taking ages for dose/tamp.
at last, definitive weights as measured on a 1 gram electronic scale just a few minutes ago:
A) The standard Silvia group handle assembly, as supplied on all current new Silvia’s, including black plastic handle and standard double outlet but MINUS a filter = 582 grams
B) A group handle assembly as fitted to all standard **commercial** Rancilio machines, configured as above = 543 grams
C) A standard generic (i.e. as used by many different manufacturers on their commercial machines) group handle assembly, configured as above = 552 grams
D) A group handle assembly as fitted to standard commercial (not domestic) Gaggia machines, configured as above = 624 grams. (Think you fill find the domestic Gaggia assembly is not identical however & is likely to be lighter).
Someone else can calculate standard deviations and a significance report!
The standard generic commercial deep double coffee filter weighed in at 27 grams (and was not included in any of the above).
No coffee filters were harmed during the conduct of this momentous experiment. ;D
Re Silvia baskets. What is a good alternative which holds more coffee. Is the Marzocco 18 gm basket bigger than the standard Silvia double, and does it fit?
The sylvia double is only 12 or 14 g I think. I suspect that the sylvia handle would be too shallow to get a LM in- they wont fit in our Brasilia. Perhaps try a 16g basket???
The "generic", "deep", double filter, as supplied by all and sundry commercial espresso machine manufacturers, holds around 18ish grams when filled - give or take - (depending on the amount that the shower on any individual model of machine sticks down into the filter when it is applied to the group) and when I fitted one of these to a brand new silvia this evening during a coffee class it slotted straight in as usual. These filters hold around 2 grams "ish" more coffee than the standard Sivia fllter and improve the coffee outa sight!

I think the reverse is more likely if you look at the design of the 2 PF types (that extended shank thing). In any case, you need to remove the handles from all of the PFs since the handles arent going to add to the heat capacity (except possibly by insulating any enclosed metal to reduce heat loss in that region). The bolt or nut attaching the PF to the handle should be included, I guess.
I recently purchased a deep filter basket for Silvia following FCs comments above. I can confirm that with the extra capacity the resultant shots (doppio)have been significantly better in terms of colour and most importantly taste. The coffee seems to have more depth of flavour than that made with the standard Silvia basket.
