Can you or can't you run 1.6 rockers on the motor?

Im running them right now(Crane Gold race 1.6:1) but I have aftermarket heads and the machine shop whoinspected the heads took the specs of the cam and played with the springs. On a stock head I think you can. Not too sure though

 

You can with the appropriate valve springs. This may involve machine work on the spring seats which means you have to take your heads to a shop. If your cam isn't too wild you can probably find some stock diameter springs that will have enough lift capacity in which case you can just bolt the stuff on. It all depends on your heads and cam.
