has anybody had any experiance with these Portflow B-Series VTEC Inner Valve Springs? i have a jdm b16a would these springs be better than my stock ones

 

yes and yes. these are meant to run with ITR outer springs from the intake
side. they throw out the ITR blue springs and use the ITR yellows and run
the inner spring setup. Tom stands by his valvesprings.

you need to use the itr intake outter springs and the portflow inner springs....
and it will go to a max of 12.5mm of lift

 

i c could i use the stock vavles or would i have to upgrade those, stock should be ok right.
