Hi all,

I plan on installing an Isky VV71 camshaft c/w Isky hi-rev kit, double wound valve springs, new valve, and guides to my 122s B20.
These parts were purchased from IPD and I was wondering what would the wear be like on the camshaft, since the double wound valve springs would exert more force on the camshaft lobes?
A local volvo 'expert' mentioned to me that the double valve springs would cause huge wear on the lobes.

Also, for those who have tried this, is there a noticeable difference in the power with the vv71 cam?

Thanks in advance
