......Or, just put the fel-pro 1008's back on it and not have to worry about it.

Now that you mention it, I didn't run into it, but I know at least one other that had to remove the rivets...
they have a viton seal, so pitting would be from the leaks you were dealing with
not defending cause i really dont care, but most manufacturers utilize the MLS design anymore.
It just seems that you missed it in your mock up stage and it cost you.

I can't mock up a engineered problem, the gasket fit good and looked good. Can't do much more than that.
NO offense man - but you never ever expect an engine to fall together without issues. Engineered problem? when you have several manufacturers going into a build like this you have to expect to check every thing several times.
It did not fit good, hell it didnt even look good - that bottom one you could see during the mockup stage
you need to look around the head to see the rivet under the deck, but it's just part of the process. Things get missed, I understand that but you really cant blame that on an engineering problem.

I used the Mr. Gasket MLS gaskets and ran into the same issue. On mine, if I remember right one rivet would get pinched between the head and block but if you turned it around it fit good. But I did ruin one gasket. Then after running the car for half a season they started leaking. I'm back to the 1008. Why I tried the Mr. Gasket's I'll never know.

He is 100% correct. When you open the cometic head gaskets, there is instructions that say if any rivits hit the head or block then drill them out.
My machinst is good friends with the guys at FelPro and they told him to lightly coat the whole head gasket( both sides) with grey silicone before assembly. I have had and ran the same Cometic gaskets since 2007 and had the motor apart a couple times to freshen up and have 0 issues with leaks. All of the composite head gaskets from felpro have a dry silicone coating on them to help with the sealing.

Nothing to see Here!
I did the same on my 410 TT Engine. No leaks at all. Heads and Block were machined for them also. When you need a custom made gasket you can not beat the Cometic. Proper prep and installation will ensure that they do not leak. I have used them on all sorts of engines with no issues at all ever.
Well talked with cometic and was told I had wrong gaskets, but in 2010 when I bought them there was only one set to buy, now they have a set for the edelbrock head new part number is 5917-040 But i got the felpro 1008's on now. Hope someone got help from this.
What part number you use??
If you put the gasket over a 340 block the rivets over hang but as you see not on the head still should not leak.
