Need some install advice

I tore down the top of my motor last night, Will be installing a stock 68' four barrel intake and carter carb. I need advice as to if I need RTV for the gaskets and where to apply the stuff. I also notced two small tabs on the end of the head, I have seen these before, they are on the head gasket and look like they hold the end gaskets for the intake. Do they lay flat? or are they inserted into the ends of the gasket material?

I cleaned the surfaces really good and scraped all of the old gunk and crap off all areas, so I am ready to install the intake tonight!

Thanks,
John B.
