Valve Springs
 

I have went into every web site trying to find valve springs that will support upto a .550 lift or higher that are the same diameter so that I don't need to machine my heads. Just compress and install. What are you using and the place purchased and even cost would be a great help.

What heads??

why don't you try contacting the cam manufacturer... thats the best way to make sure you have the right spring for your cam... if you use the wrong spring you could be in trouble... tell them what you want... and see if they can help you...
