L92 Heads??

[214Chevy]

Guys, I got a really good deal and I mean really good deal on a pair of new, bare L92 heads that I couldn't pass up which I'm going to put on my LS 6.0 for my 68 C10. Now, I do know the L92 heads have a different port on them. They are the rectangular port heads instead of the normal cathedral port heads. All this to say is, what intake does the L92 heads use? I think it's the LS3 intake am I correct? I also know I could use one of those high dollar FAST LSX intakes, but no thanks.
