Can anyone find me a part number or some dimensions of the 2L 8v crossflow exhaust valves. They should be 7mm stem but need to know if they fit in my 8v head. I think that the length that I am after is 102.6mm but I will measure this tonight. I will stick to the 38mm inlets, 8mm stem inlet but will get the valve worked on to reduce the stem within the inlet passage reduced to 7mm (or maybee 6.5!). I am putting a new exhaust on on Thursday, along with a flowed inlet and proper 8v diji manifold. I will be taking it for a tune-up after this so will get an RR graph. It will also have a RR session after I have put the head on so it should be a good comparison as to what power gain will be had. My current head is knackered ATM so it wont be all that comparable but should give me a good guide. Cheers, Chris
