As stated by Bigboy, if doing the HG's take the opportunity to install new gaskets everywhere else you can. At this stage of the game, some of the existing gaskets are not going to survive the disassembly process, not to mention you might get problems down the road.
In addition to OEM from the dealer or FelPro you can look for Stone gaskets. They are really Ishino, the same OEM gaskets in most Japanese cars. I got a good deal on those from Pelham Auto Parts.
