ls/lm head question.

in the truck is a 2004 LM7 out of a silverado 1500.
i have stock heads but have a chance to swap out 2008 chevy van casting #799 heads which i have read on other forums is the same heads as LS1's except the valves of coarse. but same CC's.

my question is they are both 5.3L engines/heads. so they should be a straight swap correct?

minus new gaskets and head bolts....

any body got some helpful knowledge i can tap into?
