I have a set of Toda valvesprings and portflow retainers, and it will be anither couple of months before I have enough money for Spec B's. Would it be a bad idea to go ahead and install the valvesprings and retainers? Or should I wait?

 

what cams do you have now ? don't install them now, just wait till you get everything and then install everything at once, less hassle.

 

They are ITR cams. Would installing the springs hurt performance with the ITR cams?

 

i say wait and do everything at once..
