Hi there im looking to buy some harvey ported headers and need to know if the ones im buying are genuine. Does anyone know if harvey ever marked or tagged them.

 

I also have a set in my shed which I would like to identify, they are ported and wrapped but that's all I know, will be interested in any answers

 

Any marks or numbers stamped that you can see?

 

none, other than removing the wrap

 

Harvey freq marked his turbo conversions but not his headers & up-pipes unless it's a very early batch , it's imposs to identify over a forum , sure Harvey & Dawn had a certain style of wrapping but that's not conclusive.....
Only power runs & dyno would give you 100% conclusion....
Do you have bill of sale , dates & location etc etc
I knew Harvey very well , there are a lot of fakes out there , so I say please if your not 100% don't advertise it as such .

Regards

 

I got mine from Harvey, just a reworked and ported standard manifold wrapped but not marked in any way. A massive crack eventually appeared at the junction and that was the end of it! Fitted an RCM GT Spec Gen 2 & up pipe replacement, so the Harvey special up pipe has been pensioned off too. No markings on that either.

 

I use the RCM GT 3 Bolt also
However I remain with the Harvey 3 Bolt up-pipe

It's all about pref. & choice can't slate anybody for that..

Most OEM Headers & ported conversions were done on trade
At the end of the day it's a manifold not the star of Gibraltar

 

Indeed just a manifold but my Bug made 425bhp with it fitted, with just a 2-1/2" front to back exhaust system too. Harvey always reckoned it was time to trade up at around 400. He was probably right as I blew mine apart at 425, maybe not related though!

 

Yea , I'd say you pretty much maxed it out
Good figure tho on ported OEM
