I have a freshly built 6.0 but have come across some big valved ported and polished 853 heads to replace my 317's. The engine is strong now but am looking to add a few more HP and put a bigger cam and better intake/heads.
I know the 317's are 71cc and the 853's are 66cc. What can I expect from the increase in CR and any negatives about installing a 5.7 head on a 6.0.

Thanks

What vehicle is this going in? I assume you are keeping it n/a?

I had 241 heads (same as 853's) on my old 6.0L block. Worked fine.

You'll probably gain about .5 compression from the 853's. Seems like a no brainer to me.
