The Triumph Dolomite Club - Discussion Forum

I have a Triumph tune stage 3 head ,i need two exhaust valves but am really struggling to find some new ones. the info from the triumph tune catalogue is part no tt10135 competition gas flowed valve in stainless steelen21-4n material and longer by 0.050".does anyone know anybody who can make up new valves if it comes to it.I rang moss when i realised they bought triumphtune but they were no help.

Hi, I can get valves made but for 2 would be very expensive. I Usually have them made in far larger quantities but they retail at £28-95 each plus vat. I do not do the long ones. Long valves are fitted because the cam has been reprofiled. You could fit another cam with a larger base circle & standard length valves, it may work out cheaper in the long run. If the car is only usedas a fast road car then tandard valves would suffice.

hi thanks for info,i did try a couple of second hand standard valves but they appaered to be slightly fater and would not enter guides.where could i get a performance camshaft kit that might use standard valves?

Try Kent cams, piper cams etc. Moss may have something. It is possible that the standard valves you tried had 'Mushroomed' at the top. It is also possible to fit standard valves with a reprofiled cam using larger shims from a Rover 2300/2600 available from RB in Lincoln, it depends by how much the base circle of the cam has been reduced.

thanks that should give me a few options
