Yep, and it's the "norm" for a 64 Race Hemi to have them (although I'm fairly certain the fuel filters should have red ink stamps not blue). That intake manifold is wild with such an early date, I can only surmise that it's a VERY early experimental piece or possibley a casting error with the year being wrong (which is not all that rare, I've seen that on other manifolds).
The filters im really not sure on. I seen em and had to have em. The intake i believe is an early piece. when compared to a 65 or later intake it has the thick front and rear flange were the later ones were thin for the cork gaskets
