Did this video help you?

wtdutton: Just´╗┐ an FYI, we are moving to a new youtube channel. check out the SPSENGINES channel.

John Gemelli: Thanks for this. I used to do them this way but now need to check spring height and pressure both installed and compressed. (manufacturer I won't mention had a spring break and said it was due to negligence by not checking those metrics when installing) BTW springs don't make any power they allow you to install a more aggressive camshaft which makes power.

346ls6camd: @chevycamaro1976 the point is to match your springs to the cam lift ...

vio333: this was really helpful thanks

chevycamaro1976: hey what is the point of switching the springs, do they increase HP? just wondering.

SoFLaZ06: I think the hardest part doing this is getting the head to stop moving around
