[DeTomaso] Timing Kit/Speed-Pro 220-3121 for 351C ?

[B Hower]

Hi All,
 
While digging through my collection of things to rebuild an engine (to replace the "7 Banger"), I found a 15 year old - new in the box - Sealed Power Speed-Pro 220-3121
timing chain set for a 351C.
 
Is there any know pros or cons to this set?
 
Thanks,
