any LS head will work. stock 862's will hurt performance unless they have LS1 valves installed.
as far as the 853 and 241 head flow, they are nearly the same. all LS heads (with the exception of 243's and LS3/L92 ect...) flow nearly identical. if you swapped a set of 241's in place of 853's, you wouldnt see any difference on the dyno, or track times. its that marginal.
