I purchased some bits and pieces from them, maybe even a carburetor (I don't remember now).  I dealt with them over the phone and they were great.  Communication was excellent and they were very helpful.  I don't know if they are an "Internet" store, since I live on the other side of the pond.

I had a similar experience, no issues

On the Feked web site I noticed that they welcome customers to collect from their location in Dorset (near Wimborne I think).  Difficult for non-UK customers I know but I find the existence of some sort of 'real shop' and a face-to-face opportunity reassuring.

Actual brick and mortor, I've had bits n bobs off them, stuffs been ok but price does not include the dreaded VAT or p&p and then VAT on the p&p.
used to trade under another name (which I can't recall) and then sons I think, Something along the Arthur Clegg and sons (thats a stab in the dark could be way off), near Portsmouth I believe

I bought bits from Feked online, including my exhaust system. No problems.

OK guys,

 It sounds like it does not matter what kind I get, JP, GMP, Wassel- they are all about the same I guess.

 I think I will just buy a set of OMEGAs' (Taiwan I believe), because I can get them over here.

 I thought there was a time when you could buy Wiseco for A10, but I see nothing on there site. Thats too bad, because that

 is quality stuff. *sad2*

I about to fit some Wiseco pistons.  On the box it says
7949MO7000
Vic Eastwood A10 2vp domed,
Clear: 0.0040 (0.102mm)
2756xc  cw19  S746
092210/0/aa/6839

They are only slightly domed, I'd guess about 7.25 ish

Think my Flash has 7.25 and they are I believe flat, so possible yours are a bit more.

Only one problem.  As they are symetrical with equal cutouts for the valves, not sure which way to fit them!  Any suggestions how I can find out?  Does it matter?

As they are symmetrical

means they are the same so does not matter, asymmetrical = different one side to the other

Whilst they look symetrical to me, it may be I have missed an orientation feature, oilway or marking.  I guess then they would not be symetrical?

My recollection is that the wiseco's are 9:1.
If they have a dome that would be the case. The 7.25's are flat tops.
The 8.25's have a cone type shape to a slightly raised raised flat top.(sometimes also described as 8.5:1)
The old school 9:1's have a soft curved dome.
The 10.5 and 14:1 are clearly high comp with clearly high tops. But all the more normal ratio pistons are not that dissimilar in dome, being none to bugger all.

would think if the were asymmetrical they would have a very clear marking to indicate which way, don't know that you could get any other for an A10 but me having only bought three sets in my life means I'm no expert *smiley4*

If they are not slotted (early golden flash), do not have differing valve cutaways, or an arrow indicating fitting direction on the dome I would say they can be fitted either way around.
