What is applied to ARP intake bolts going into aluminum heads holes exposed to oil, sealant or anti-seize?

Intake Bolts into Aluminum Heads - Sealant or Anti-Seize?

Either will act as anti seize. Only the sealer will seal properly. If the intake bolt holes in the heads go completely through to the valve cover area, sealer. If not, anti seize.
The bolts thread into the block, so really no antiseize on threads, just a sealant on threads.
I don't know why I was thinking intake bolts, but that's what was on my mind. I agree though. I use sealant on every head bolt I install. Blind hole or open. It helps keep them from rusting either way.

Subject is correct and I edited the text. ARP Intake bolts into aluminum heads. Sealant or antisieze into the open holes.
Maybe that was it. Thanks. It's usually my stupidity. Maybe we can say this time it wasn't? LOL

Anytime I'm threading a steel bolt into aluminum threads, it gets anti-seize; usually copper. Same with spark plugs.
If you don't, you risk stripping the threads on removal.

Red X, I know I haven’t been around these things since the dinosaurs roamed the Earth like you, but it would make sense to give the bolt a little love lube to stop dry holes, which if I’m not mistaken you implied to know everything about…

Me too as a kid. Always wondered why I had puddles of oil on my intake.
The Trick Flo small block heads , the intake threads are all blind holes. So no coolant or oil leaks through the threads

You'll need to check the head to see if it will be wet or not. If wet (oil or coolant) the sealant and torque to factory spec. If dry use ARP lube and torque to their spec.
Do yourself favor and mock it all up with the intake gaskets and verify the china wall seal clearance and the bolts fit.

It would depend if the holes had inserts in them.

No inserts and holes are wet.

Thread sealant or rtv or you'll wish you did.
Just use the sealant on every bolt - you can't make a mistake that way. Sealant in a dry hole will just act as lube.
