Can i bolt down my sbc manifold onto my centerbolt heads?

i have centerbolt heads and a older style holley dominator manifold can i bolt it down without those 4 center bolts that would have to be angled?becuase this manifold i may not be keeping for long so i need something that i can bolt on to my motor until i buy the correct type of manifold and i dont have the old one anymore i was wonder what would be the side effect for having those two bolts on each side missing?? and will i have an leaks or should i be ok?
