You will need to be more specific about the type of engine and what you are trying to achieve.

It's really cheap if you just pour sand through the air intake with the engine running. It won't do any damage I promise... A mate did it.

8v cylinder head > get it mildly ported and polished.
camshaft > get mildly reground.

not after huge performance gains

Is this on a Polo?

Don't bother.

Why? It was a sensible reply. If it's on a Polo don't bother, if it's something better then maybe.

Is the flow rate and cam profile the major bottleneck on this particular engine? How have you come to this conclusion?

I had a new cam, seals and a skim for £150 all in at my local engine centre.

Cam was the most expensive part (£78 IIRC) so unless you cant get hold of a new cam (unlikely) dont bother messing around with the old one. Regrind a crank, bin a worn cam IMO

oh well thanks for giving your opinion WHEN NO-ONE ASKED FOR IT! i simply asked how much something would cost and end up with completely unhelpful arsey comments, i do not care less whether you think its a good idea to work on certain cars hence why i didnt ask for it, so dont share it!

see look andy xr has got the right idea!

Most flowed and ported heads are around £300 upwards, if it is a VW you are probably best off contacting some one like TSR.

For you to port the head yourself - £10 in parts.

To pay a professional to port it £200 minimum assuming your not increasing valve size etc.

Benefit (unless your engine has a particularly badly designed head which I doubt) 2-5hp at a guess assuming you use the hotter cam and a better exhaust (this doesn't just mean a cheap loud system it needs to flow better) and better flowing inlet (probably not a cone filter).

The guys above are basically trying to say your looking at a cost of probably circa £500 to achieve virtually nothing except bragging rights, no-one will be particularly impressed and you will struggle to feel any difference.

Seriously stick the money in a jar and in a year or two put it together with the money from the sale of the Polo and buy something quicker and more fun. Or blow it all on coke and hookers.

Fine, if you want to waste all your cash for minimal return on a shopping car.

You'd be better off putting the money in savings to buy yourself a sports car sooner.

Lovely stuff guys, keep it up.

But, to answer your question, head work will vary massively depending on who does the work, if you want it done properly, with someone putting the head on a flowbench and getting decent gains, then you could end up paying very large sums, even on an exchange basis, you get what you pay for when it comes to engine work.

Does help if we know what car it's for though, you'll be surprised at what people could tell you about that particular engine, and what is and isn't worth doing to it.

Ignore those who say don't bother, it's up to you what you do, but sometimes it isn't worth it.

We still could do with knowing qute what level of head work you want and what engine it is, as it may make a difference to the work folk will suggest you get down. It could be a V engine, in which case all prices just doubled. It could be DOHC, in which case cams will be more, as there's 2 of them. If you're looking at doing some relatively minor, but still expensive work, it may even be cheaper/better to just change to a newer 16V engine for example.
Just asking how much some head work and a cam will be is like asking how long a piece of string is!
