Did the jdm spec C heads change when the 09 hatch specC came out, or was it given more restricted heads, as the rcm description suggests? I only ask because I am trying to get to the bottom of an issue, and if I did have cracking around the threads I would be interested in these ones, but it would be a few weeks before I can find out.

No Cams are for uk heads in JDM heads
The pick up is different. You can modify the heads to move sensor into position or these RCM cams have the pick up location in the correct position.

Regarding heads they have had the throats manipulated via CNC to allow max flow.
All mold flashes have been addressed.

The head and cam combination we happily support big numbers.
The big advantage of these heads is the volume they will be capable of flowing high up the rev range so power band won't just die off!

Hi mate, think you might want to adjust your prices slightly as the heads are only £1450 brand new from import car parts.

https://importcarparts.co.uk/parts-info?id=12776&cat=96&sub=183&sec=385&var=33&dc=0&g en=&searchKey=&searchPart=

Good luck with the sale.

There is different versions of the heads
I can prove what I paid, and have been told that mine are indeed the proper ones.

At this moment in time No price adjustment is required

And even working on them prices with the work done on my heads makes them cheaper at my price than you buying and doing the work! ��

No it's fine, before I posted I did work out cost with your heads and machining, I may have adjusted price if after work done and price had exceeded. But it doesn't.

I can only say what I've been told and that's there are different variations of the JDM big ports. These are the desired ones.

I was told different but I could well be wrong so will apologise if so.

Even what I'm asking for money wise it works out cheaper buying mine than buying the others and having the machining done on them.
