The RB holley manifold does not have coolant holes. Will the o rings in place plug the flow or should I use gasket sealant there? Never installed one. Someone said use quarters? Sounds shady. Any help appreciated.

You can tap in the right size freeze out plugs and then if you ever remove the intake for any reason the coolant will not come out at all. One of the sites sell them... Pineapple, Mazdarix...??? I forget which one.

Look up the size and goto a local not comercialized autoparts store. Not autozone oreillys or advance auto. (these guys dont carry a selection of freeze plugs behind the counter. I think its 21mm but not sure. they are like .50 each, maybe less.

Quaters are too big use pennies or nickles.

to answer ur question, yes the O rings will seal. no need for sealant or ur spare change. the other alternative is freeze plugs. their either 20mm or 22mm. saw it on the site but can't remember which is it.
