If you´ve upgraded your springs, what brand and specifications are you using?Even though my cam (XE270HR) with .512 lift and cobra intake won´t support too much beyond 5800rpm (if so), I think it´ll be safer if I had upgraded valves (another mod I´m thinkin is 1.7 rr). It´s not in my plans changing cam by now, in case you´re just wondering.
I appreciate any info.
