I've been told by numerous people that when running the 806 perimeter bolt heads that you have to run stock gaskets due to a little "notch" on the underneath of the head. Running any other head gaskets ('99-later or cometics, etc) would cause a leak. Anyways, so my question is can you run these 806 heads on a iron 6.0 block and use stock '98 head gaskets?? I'm not sure if you could or not since the difference in bore size. Any help?


thanks!

Well the problem I see with running stock 98' head gaskets is the the bore size is going to be too small.
I'd image somebody out there makes something that will work but I don't know who. Sorry.

Anyone else? I guess I'll have to call some sponsors tomorrow... I really want to keep these heads.

If you are running any head on a 6.0 you have to use the 6.0 gasket because of the bore size. The 5.7 head gaskets will hang over into the combustion area if you use them on a 6.0.

Yeah, that's what I thought... like I said, I don't think you can run 806's on a 6.0 then...

Anyone want to answer what type of gaskets can be used?

I never found anything out. I went with 317 truck heads instead that were stage 3 with 2.08's

Yeah but I know people have done it I have saw it listed before in some sigs. The 5.7 head gasket is way to small. All I feel you need is a single layer or composite type gasket.

Anyone with any help on this will be greatly appreciated.

NVM stock 6.0 MLS gaskets seal fine.

the ls1 heads have a smaller bore size and would hurt the 6.0 perfprmance,not to mention a smaller runner,317 heads worked a better choice
