bigger valves or port nd polish

[dub-disaster]

ahhh i seee offsetting that makes sense

Precisely why the chap who did mine wouldn't warranty with larger inlets as well, unless i had off setting done.

Here's mine.

[polo classic]

Well, my head (not my two shiny ones) cost almost £800 when I had it done a few years ago. Still not fitted it. It will go on my 1473cc 1W bottom end I have in progress (sort of).

800 is not that much when you consider how much money that has gone into the bottomless pit called my G40 lol

[Nick_S]

Think mine was near £600 when you add in the price of the larger valves. Buy cheap, buy twice!

Auro- without knowing the rest of the spec you can't say too large. They are very big though, and I'd expect the distance between the water jacket and port to be very thin.

Porting quality looks good though- lots of time been spent on that.

Yoof,

I hv standard cam, GT inlet manifold, 4-2-1 exaust manifold, injectors 660 cc Siemens deka (hv stand alone management) nd 65 mm pulley on charger
so I would like to do port nd polish. If this is oversized I could tell the guy don't do so big porting.
Company which is dealing with this kind of tuning is called TK-Motorsport fm Austria nd what I read on German nd Austrian forums lot of guys say he work perfectly nd the price is 500€ (app 430pounds)
