i am currently running a comp cam valves springs and tit retainers with dual valves on intake and single on the ext along with the comp stage 2 cams, my question is i am going too be using skunk 2 stage 3 cams and wondering if it would be alright if i was too use a stock inner spring on the ext for a little more protection, and would it mess anything up

 

ITR intake outers and Portflow inners all the way around.

 

but i dont have portflow i have comp can i just use the b16 inners with the comp ext outers

 

Those valve springs will coil bind with Skunk Stage 3 cams. The ITR/Portflow combo is an economical (read cheap) way to go.

 

Cheap is not a good idea when you're talking about your valve springs, you don't want to break them, i've been through the headache. Get a set of crowers, worth the money.
