Cylinder head coolant ring

[Jamo]

Can anybody confirm what this process is officially called? and how much does it roughly cost?

Steve at Hockly Heath has the program to have this done via spark aroading

Steve with Red S2 and Autosport curry fame?

I've always known it as 'deck cooling' and JP can do it, not sure of cost though.

AFAIK when I asked him about it a while back it was about £200 if done at the same time as getting the head resurfaced

[terrybullwon]

The very same he can do the block as well

[Error404]

I was wondering the other day if it was worth doing the block aswell?

[Jamo]

Yep error Repo told me he got I think it was 50 bhp from this mod with the extra timing you can run

Can you still use the stock head gasket?

[spink]

I remember someone was selling a head on here for BIG money a few months back with this done to it,think he refered to it as a 'works urq' mod or similar.He was very cagey about it though and wouldnt provide pics when asked as it was a secret

Yes.

Give him a call.....

Is this to improve cooling overall, or more even cooling reducing hotspots?

[G60Rallye]

The idea is to get more cooling through the head to reduce any chance of the head warping. More power should be available as you should be able to add some more ignition timing. Yes you just run the standard gasket Jamo.
