Tabs under intake manifold?

[Sonny]

I am installing a new aluminum intake on my '70 318. This is my first Mopar. I noticed that at the ends where the rtv goes on top of the block there are 2 tabs under each end at the head. Do those bend up to hold the intake gasket or bend down? Mine were down but buried under the old rtv. Its also making my intake sit too high.
Also the round pin in the picture I'm sure is to hold the end gasket it in place and align the intake. My intake doesn't have this hole. Can I just cut it off? I know the gaskets are on backwards . Just on for reference.

Those tabs are from the head gasket. If they're interfering cut them off. The pin could be removed also. Just use a good sealant on your end gaskets so they don't move.

Thank you!

Some gasket kits have holes precut on the manifold end gaskets using the tabs and the pin to hold them in place during installation, either way works.

Original ends were cork and the prongs fit into holes to locate it. The center pin did the same. Remove the center roll pins, and either push the head gasket pins down, or cut them off. Use RTV on the ends, and NOT the cork pieces. I have seen too many engines leak coolant into the engine because the ends hold it up just enough to create a leak.

I agree they can cause an issue.......

they're for locating the end rail gaskets.

Anyone know the torque spec? 25-30 ft/lbs?

Right again! I forgot about that one. Been awhile.
