Are these new or old style head gaskets?

Those are the same pos gaskets I had issues with. Supposedly those were the lml style. Now they are back to the gaskets that are fully covered in the black sealer
I am about to do mine ? 05 , what is the part number for these victor ones ? the reply in my post says to use the LML gaskets ? which ones should I be using ? I only want to do it once ?
I havent heard anything bad about the LML gaskets...I believe Mark Broviak said he uses them and they work just as well as the older riveted style.
I coat the gaskets with this both sides before assembly as well
Why would you do that
a band aid to help things last when you dont do things the correct way :spit:
that would be my guess.....
Why not?
Too me just a ease of mind.
Especially when OEM specs a warpage limit on the heads. While I couldn't put a .001" gauge under a straight marble edge that's 12" long on my head.. That doesn't mean the head isn't "wrapped" per OEM specs
Short answer. Avg milling doesn't even come close to roughest part of an RHR chart

If the head and block and prepped correctly there should be no need for the spray sealer , I could see how that may contribute to a failure if surface prep is under pare ?
I used felpro HG gaskets in my 2005 Viper and they call for no spray sealer ? leaked like a bitch , they covered another set , but I followed the manufacture directions and sprayed them , and no problem after . I do not see anywhere that GM recommends spraying them ? so I think it would be a personnel experience thing , but if guys are running 700 + plus horse power on stock GM gaskets in stalled dry I see no use for the spray either ? just my opinion ,

If a gasket is designed and tested to seal given a set of prep instructions, and they commonly have no issues when installed that way, I see no reason to spray. At that point, it's either unnecessary or actually going to hurt sealing.
These aren't old school asbestos/paper layered gaskets that need copper. With multi layer stainless steel gaskets, spraying something between the gasket and the block/head can hinder sealing... the coatings are designed to be on bare metal.
