Default Valve Springs

hi everyone, im almost done with my heads/cam swap. Since this is my first time doing heads/cam i just wanted to know if the valve springs, when torqued supposed to be "not level". Like every other one is a different height if you know what i mean.... im guessing its normal because the size of the cam? (MS4) sorry for my newb ?..... thanks!

Once torqued they are not going to be the same height depending on the lobe that the spring is on once torqued.
Did u get the right springs for the cam?
Remembering that the MS4 has a 649 lift intake so you don't want that spring to lift to 650 only. Why you ask because your pushing that spring to just about the limit every single time.

Wow good timing (pun intended), I was going to post a question about valve springs also.

Just need .570 max lift, where can I find the best prices for a set?

Thumb of rule .050 more than your total lift. My cam is a 600/600 intake and out my springs are good to 650 Patriot Gold Extreme.
