What sealant to use

Ok I have prc 15 degree heads, and I’m finding oil on top of my intake manifold buy the bolts. I’m reading and it seems that is from the rocker arm bolts on the intake leaking. So I got some arp thread sealant, but everything I’m reading is saying blue loctite or black rtv. Will this arp stuff work?
thanks

Any of the above 3.

NOT RTV; it dissolves in gasoline. NOT Loctite; it doesn't seal.

ARP thread sealant contains Teflon and is what most, if not all builders will recommend you to use for sealing the rocker bolts in the ports. Now, having said that, I’m not so sure that’s what your issue is here. Leaving the rocker bolts unsealed in the intake ports will cause it to smoke and will foul spark plugs. Oil up on the intake? Is it puddling? Can you post a picture of this?

This, you shouldn't have oil on the outside of the intake from leaking rocker arm bolts
