I just want to tell everyone to not use HD valve springs. I just smoked my brand new Kitaco cam and rocker arms!! was only ran for about 3 hours.. I guess I should have done a search on this and seen what people have said about them before I used them. :cry:

This isnt the first HD Valve spring horror story ive read. This is why I was told to use xr70 valve springs, which are stiffer than stock but not so stiff that they ruin anything.
