Mahle head gasket orientation (Page 1/1) Lilchief AUG 29, 07:59 PM Putting my 3.4 together and the head gaskets aren't marked for what's top/up. There is 2 little strips of metal that runs from one cylinder to the other, only on one side. That's the only difference I see. Any advise ? Blacktree AUG 29, 11:45 PM Which Mahle gasket are you using? The one I see listed on Summit Racing for the 3.4 V6 has "this side up" stamped on it. https://www.summitracing.co...rview/make/chevrolet Zoom in on the photo, near the upper right corner. Lilchief AUG 30, 12:29 AM Thanks Blacktree. This side up is not on my head gaskets. But I can match the odd holes at the bottom and get it right. Are you ready for the hurricane . My yellow 88 is in Leesburg. Hope it survives. Thanks for the help. Blacktree AUG 30, 08:18 AM You're very welcome. I've been in Florida since the early 1980s. Hurricane preparedness has become second nature.
