5.3L heads with 71cc Chambers? I have been seeing a lot of 853 and 862 casting heads being advertised as 5.3L with 71cc heads....I have looked up the info and every thing I have seen says they are 61cc heads...the 71cc are only found on the 6.0L. Am I missing somthing here or are the people posting on E-bay just wrong?
If their new heads then those on ebay are wrong.
If they are some kind of custom set (which wouldn't make any since) then a 71cc 5.3 is possible.
I had a set of 241 heads done and wanted lower compression. We had them finished to a 72cc head.
I doubt the 5.3's are a 71cc head. More then likely the ebay guys are wrong.

from E-bay guy..."Actually all the service literature we have on these state they are a 71cc chamber."
