Well let me rephrase, for your application it is unnessasary to use weaker springs to break the cam in and yes it is a MYTH for an application like yours. What is your pressure over the nose? 320lbs?
waggin, It no myth.....I sell aluminum cylinder heads set up for up to .700 lift....
Just because a cam has 700 lift does not mean that the spring pressures are over the limit and require the inner springs to be removed so the cam don't go flat. Some guys use Beehive springs that have no inner spring. What do they do?
I am not saying that people don't do it, I am just saying that it is unnecessary in most cases. People like to say that my cam did not go flat because I took out the inner spring.....they say this because they took them out and that is their experience. I am saying I leave mine in and I have never had one go flat yet.
Most guys at 700 lift would go Solid Roller and the problem is gone all together even with the High Spring pressures.
