Preferred 351W Block??

I have heard / seen several reasons why one 351W block may be more desireable than another:
To qualify for emmission exemption (older is better)
Thicker webs ('74 and earlier)
Slightly lower / higher deck heights ('69 & '70 / '71 on up)
Are there other reasons? Other than for emission qualifications, are there really significant reasons to go with one rather than another? If so, which is the most desireable.
Thanks,
