hi bro. i changed mine without change the valve spring but i just use regrind camshaft from matspeed. from dyno i managed to get 10 whp increase ( might differ, depends on engine) in my NA engine.

If your camshaft lift is higher than stock ones, i suggest you to go for harder valve spring so you can avoid valve float. Valve float is one of the reason which can cause decrease in high rpm power.

just my 2cents.

Thanks for replying !
My car is Turboed .. and plan to using piper cam 272...
For example : If I install the camshaft.. I wont rev over my motor.. I'll still stick with original rev which is 7.8k rpm... Hope stock valve spring can hold it !
Coz.. I dont want to change valve spring... just buy camshaft and drop in !

There's few cam that have lower degree such as 264, 268, 260 that does not need any valve spring change.
