I need to find a set of 1.9 Intake valves.

The current valves have a 4.5cc dish on the combustion face. I would like to reduce this rather than maching the head surface to reduce the over all  volume of the combustion chamber. currently 85cc and I want it at 80-82. Reduceing the head gasket isn't on as the squish is where I want it now.

 

Apart from KPMI Black Diamond's any one know of valve manufactures I can talk to.

Manley  1.9 valves go into all the heads I get done

 

 

Are you sure of your measurement ozy. Would have to be a pretty big dish to get 4.5cc. Can't see any other way of achieving 80-82cc without milling the heads. Rob.

Speaking of intake valves...where can i get a set of 1.94" Intake units for an 86 EVO - I am tweaking the heads a little over winter.

Rollie's carry the AV&V line of valves. Not sure if they do Titanium. - Rob

thanks guys
I got a lead on some from KPMI if I need them, they will custom make valves. Correct Rob not cheap but in the scheme of a new build $200 is fuck all

Also looking at just decking .030" which should get me there. First need to check clearances to see if decking will fix it with out causing other issues.
It seems they were a little over enthusiastic with the chamber grinding.
Next few weeks will sort it out but at least I have a few options now.
