I've got a little coolant coming out around the passenger side of the manifold and a puddle above the front furthest left cylinder behind the valve cover. My intentions are to change this when I get up to NY this weekend so I want to get the parts on order now, as AZ has most of the parts as special order. Does anybody have pertinant GM (or other) parts and PN's or related that should be replaced? I'm looking at zzp now and have (based on previously read thrds):
-injector o-rings
-oem L67 SC gasket
-aluminum manifold gasket

99 gtp stock, with plans of modding in the future.
Thanks, Ted
