Hi.
Anyone in here that can answer if the Cam profile 120/104 can be used with new stock valvesprings and retainers? I am firstly thinking if the stock springs can handle the ramp acceleration of the 120/104.
I have safely used original valve springs with amongst others the 964 profile without any problems in an earlier engine,
Would be very happy for any answer.
I have been using Aasco high performance springs and TI retainers untill now, but fear that thats most of the reason for badly worn rockers and camlobes.
So I really hop some of you in here can share som light on this.
