i have jun type 2 cams. i currently have itr outer with portflow inner valve springs and titanium retainers. should i upgrade to jun or toda springs or stay with my current setup? i wont be going past 8800rpm ever and i dont go to the track often. i am just wondering if i need to change since i am hearing all these stories on here about springs binding and portflow springs/retainers and all? or i am just being really paranoid these days?

 

I'd always get the cams and valvesprings from the same manufacturer. They're designed to be able to work together. Sure other combos may be cheaper, but I'd pay a little more for piece of mind.

 

You can also buy Toda's and have piece of mind..

 

thats what mike at ips said, hmm this is going to be interesting decision
