So I’m gonna do heads and cam. Ls3 heads and not sure on cam yet but I’m wondering if someone can put together a parts list on what I need and should replace exactly .... other question will my headers work with ls3 heads even though I have ls2?

Start reading this:

and:

I'm bolting on LS3 heads and intake this month, replacing lifters, lifter trays, pushrods, head bolts, and rocker trunnions (if they come in time). The heads I bought already have the BTR .660 springs. I'm not replacing the cam at this point, but you'll probably need a timing chain and oil pump to go along with the cam swap while you have everything apart.
