as said highly recommend Craig (stan*) @ ap developements, recently rebuilt my head along with port work and gas flowing etc etc. no problems at all
what sort of prices to do the work???
Echo this.
Lol open a can of worms why not! Many many (and generally poorer tuners), will gas flow heads for peak power, high valve lifts e.t.c, this can lead a piss poor engine.
From memory expect around 5% - 10% (could be wrong!) gains in flow accross pretty much the entire rev range, which will be a directly proportional increase in torque and power. It doesnt sound a lot, but it makes all the difference.
Craig will make the head bespoke to you, you tell him if you want a gas flowed head for rally race engine, or a head for a road car and he will do as per your needs. Most cheaper engine tuners will be scratching their head by now going ... "so you want a stage 1 head yeah?"

Golf GTD Mk7
Oh and that costs £800 btw
Not sure on the benefits on a NA engine really. If is was turbo'd/SC'd it might make a bit of difference I guess.
