I guess I'm pulling heads.  Failed to clip those little tabs from around the alignment dowels.  At least I havent mounted the intake.

Not sure, if them wee tabs make a difference with later engines. Once you install the gasket they should flex and bend enough to align anyway. Dont know when the tabs were used, but i never bothered with trimming them.

The key for a proper seal is copper spray. I wont do a head gasket install without it.

I've never removed them.  I think they were put there so the same gasket would center no matter if it was a gen2 or gen3.  The gen2 alignment dowels are smaller.  They flex out of the way.  Like 304-dude said, copper spray on the steel side, always.  Never had a failure with Fel-Pro.

Well I can't say one way or the other if it matters or not but... the Felpro paper insert shows...
But y'know, I would imagine very few folks actually trim those tabs...
And boy, unsure if I would pull installed Heads after realizing I had failed to trim those tabs... ugh...
For assembly, after cleanliness, man... attention to details... stinkin' little details...

Wow,  I've done hundreds of engines, and never removed the tabs.  Never had a failure caused by not doing it either.

I must not have had that particular gasket set or notice... Since it states when slotted cap screw hole is supplied.

The times I did head gaskets installs on AMC v8, none had the tabs, and laid flush without any effort to fit over the dowels, as if I missed noticing them. There has never been a time where I have not skipped a dry fitment with gasket and mating surface. So, I assumed the tabs were auto adjusting, and made question on when the tabs were introduced.

IS IT possible, depending on the gasket set, that the tabs are not present? The time I did the installs were back in the mid 80s and 91.

I would think once one fits the gasket in place, it would be very noticable enough to see a fitment issue. I assumed in my first reply that the tabs were made to be self adjusting... until I read the noticed supplied in the recent reply, and now know there is a proper procedure to the use or removal of the tabs.

I'm not kidding that I failed to remove them.  The instructions read like it really REALLY matters.  But if all the cool kids are leaving them on without issue then stay they will!  Thanks, guys.  

I did check my spare heads and there is a generous chamfer around the dowel that seems like it has room to spare for the little taps.

I'm wondering if Felpro is having gaskets made fore them. First head gasket failure ever on a new build.
The one side of the gasket didn't have a "textured" surface by chance?
Never seen ones like this and will never use them again!
