Valve springs

[sm00th]

Im looking to upgrade the valve springs on my v2 head. Ive heard that someone put 450 springs in does anyone know what 450 they come from.

Cheers

The valve springs that come in the V2 are pretty good.
Any reason why you want to change them??

There is no way it should float. if it does I would dare say your over revving it.

As for your original question, I am pretty sure it would have been a custom build or something like that. Using any other type of valve spring would take a lot of machining, and would not be a simple bolt in affair. There are a few guys you could ask about doing it. Terry from Firepower Minis could be a good first option to ask the question.
