Is GM using 6.0L head gaskets on 5.7s now?
I ordered some GM LS1 MLS head gaskets from Scoggin-Dickey and I was sent 6.0L gaskets. I called S-D and talked to the parts guy and he did some research and said that the 12498544 part number is now for 6.0L gaskets and that there were no more 5.7L gaskets. This doesn't seem right to me. He told me that if I found some 5.7L gaskets I could return mine, so that's what I'm trying to do. Does anyone have any insight on this? Is there a different part# for the 5.7L gaskets?

My buddy bought some 5.7L ls6 mls gaskets last week at a local chevy dealer. I know they are 5.7 as they have the stamped tag on the sides. Might just be remaining stock, but they are still out there. Let me know if you want me to pick up a set.
