Now, after searching these forums and looking online on various places etc.

Does anyone sell or manufacturer equal length headers/extractors for N/A made engines? Coming from a Ford and non-boxer place prior to owning these cars I find it odd that the only offering is a unequal length variant purely for noise that has no real performance enhancing properties. 

Can anyone enlighten me or explain why that's the case?

I have an SF5 Forester 2.0 non turbo sohc version, the heater fan wasn't blowing / working at all, went to the wreckers today to grab some bits and bobs for the interior that was missing from previous owner etc and I grabbed another heater fan blower unit.

I plugged that all up and it still wasn't working and from googling and that my problem might be the Heater Fan Resistor but I am looking at a PDF of the Forester Workshop manual thing and I can't see to see the location I have that RHD is different from LHD models.

Does anyone have any input to suggest were the resistor is located?

I've used the search feature and come up short.

First off, please if I've posted this in the in correct place please move.

Now I will hopefully (if I can get someone in Bathurst that actually knows how to sell the correct gasket set) attempting this on the weekend on the forester.

For some reason a single side is called a 'set' (I would have assumed a 'set' meant all that is required be it left or right or quantity of 2.) Also I do love how automotive retail works for example;

a 'set' that contains spark plug tube seals, 5 bolt washer/rubbers, 1 large circle seal and 1 small circle seal.

Burson's; $112 (x2 would be $224) (may aswell get local Subaru dealer replace them minus sparkplugs)
Repco; $99 (x2 would be $198)
Autobarn; $89 (x2 would be $178)

And lastly Supercheap; $42 (x2 would be $84)

So SCA will be the winner but they have a RCG308KS on the shelf but say I require a RCG308K and after googling the KS variant says basically most if not all the SOHC 2.0 Boxer engine models known. 
Does anyone know what the difference is?
