Anyone know of any companies that well custom make valves or if Howell or the other company starting with F (no idea) makes valves over 1mm. I would like to get 2mm oversize or maybe somthing different. Please no lectures on the waste of money and the non-benifits of oversized valves. You know what they say, whatever floats your boat.

Ferrea can make any sized valve you want.

a local dsmer i know has 2mm oversize valves, not sure where he got them though but probably ferrea

thanks.

Eh, I lost a considerable amount of low end torque with 1mm oversized valves, I think that 2mm would probably be overkill. Just pick a good camshaft and it will provide the desired effect.
