What valve spring should i get? Is Patriot Gold ok? or PAC 1218? or maybe suggest me another spring to use.
I will be running:
-Comp Cams Pro Magnum NSA 1.6RR's with a 7/16" stud (guide plates, harden pushrod ect..)
-Stock Cam
Future plan will be Ai 230 / 238, will i end up having to buy springs twice?

I'm using VS2700 from bullet racing and I did have 1 break, but that was due to improper installation. So far though everything else is good since I redid everything. And the springs use stock keepers and retainers. I haven't revved past 5800 yet though because I haven't tuned it yet. But my tune is coming in the mail tomorrow afternoon. So I'll repost after revving to about 6500 and let you know if my engine is still in one piece. Lol.
I have 1.6rr's with a CC503 grind.

Yall's responses are appreciated, still trying to narrow things down. Don't want to swap springs twice, but if that will save me from future problems might have too.
On another note, whats max lift on stock cam with 1.6RR?
Is some of the springs mentioned in this thread too much pressure for stock cam?

comes with everything youd need. except a valve spring compressor. you can get a "tims tool" or for $100 you can get the crane setup that is also sold at byunspeed.
i dont think youll have any such problems running those springs with a stock cam.

Stock heads? No point in going over .600 total lift. Of course somebody is going to argue with me.

The reason a few are saying run LT4 springs now and buy better springs later is because the LT4s are cheap and about perfect for 1.6s on a stock cam. You buy a more serious spring now and one you will be putting wear and tear on it, and in a performance application valve springs are a wear item. Second, plans change and maybe your cam choice will change or a better spring will come along by the time you are ready for that.
Far as stiff springs on a stock cam, it would probably handle it better than the cast cams a lot of guys swap in.
