Comp Cam 401 Nailhead

[Grhopperass]

I have a comp Cam whith the following specs.
Rocker Ratio 1.6
Valve lift on intake / exhaust .464 , duration 288
Cam lift .290
Is this too radical for a street machine?
I've read somewhere that these cams are hard on Nailheads.
Is there any truth to this.
Your guidance and thoughts are greatly appreciated.

IF, is duration advertised or @.050"??? More than likely with stock rockers your actual lift at the valve will be closer to .420"-.425" give or take.
