Who runs Harvey's Ported Headers on a Classic ? Opinions please.
As above. I'm interested in Harvey's ported and wrapped headers plus matching up pipe but these are not cheap as for standard modified headers. Could you tell me please if these are that good as Harvey's says.
Thank You
Thank You

Will do mate I was being lazy
Blimey exchange rate, might have to buy some OEM headers then as mine are aftermarket jobs and the OEMs go for £25 to peanuts.

What else are you running on yours chap? Might be worth listing up in case Harvey replies and can give you more details on how they'll improve your setup.
I'm running a VF35, ECUtek map, FMIC, Walbro pump and induction kit with 336bhp and 298lb/ft but would like more torque.

Quicker spool, lower down the rev range, more torque.
Harvey has done a LOT of work on gas flowing and knows his stuff.
The WRONG choice, especially up-pipe, can make the car slower

i hear only good things with these headers under 400 apparently better than any aftermarket jobs. he s a very clever man speak to harvey he will do his best to help u even if your not buying an item off him. Im sure u get bit more bhp but mostly more torque and drivability

I'm not saying that his headers are NO Good or anything like that. I was just wondering how different they are to headers I'll port myself for example. Just asking for people opinions if they're really worth the money. I'm VERY interested in these but I though maybe I'll try to do it myself and save some £.

I gained 400rpm of spool with a set of Harvey ported headers and up-pipe vs OE plus power also increased on the remap.
I'm currently running at 440BHP on ported headers with un-matched up-pipe (I've swapped the turbo since getting the headers)

I also agree with this. On my old classic Uk turbo it made a big difference to torque and spool, especially if mapped on the car. they a re a cheap and VERY worth while mod for a standard or lightly modded UK turbo

But, as I've tried to point out, you might end up with worse.

You will get better spool, a more willing and crisper car with noticably better torque. Your turbo will develop the same boost at less duty cycle or more boost at the same duty cycle. I do not make any unsubstantiated claims, some of my customers have already shared their experiences with you and I have not received a single complaint from anyone that has fitted these over a number of years.
There is porting and there is porting and my porting has been developed over a number of years with the use of gas flow bench equipment. From time to time I take back headers in exchange which have already been ported and because the person carrying out the porting has not understood what it is about they are scrap. It is not a simple matter of opening out the port diameter to get the results I get consistantly.
The benefits and commendations for my ported headers are numerous. Just do a search.
I also supply GT2 Spec tubular header sets but there is no point porting these. What is worthwhile on the tubular header sets is DEI heat wrapping and swapping the supplied uppipe for my trick 3 bolt uppipe which greatly improves spool and torque as many people have found out.

+1 Harvey,your work is second to none and I for one have one have a 'trick' uppipe on my GT2 spec headers and gained a good chunk of torque and 600rpm better spool.
Your the man Harvey
