Will these cam specs work in a 5.3?

I have a lq4 that through a rod. I would like to keep the same cam that I have but I'm need opinions of if I might have clearance issues. I am gonna run the 317 heads on it FYI.

Cam specs are:

Adv. Duration 260 and 289
Duration @ .05" 211 and 239
Lift .600 and .623
LSA. 113

Why so much exhaust duration? I'd be surprised if that cam would fit in a 5.3 without flycuting. Hopefully someone else will chime in on this.

Admittedly, I don't know a whole lot about choosing a cam for a given setup. So I told Texas Speed what I was planning (turbo build) and they sent me this cam. It made great power in the lq4. Made 396whp through a t56 with the cam, longtubes from cx racing, and a single outlet 3" exhaust. That was N/A with stock timing also.
