I am in the process of installing a set of aluminum Edelbrock RPM heads on my 350. I was actually reading the installation instructions and Edelbrock says to use Edelbrock Gasga-cinch or suitable thread sealer, and ARP (the manufacturer of my head bolts) says to use ARP Moly Assembly Lubricant on blind holes and ARP Thread Sealer on water jacket holes. The machine shop I use claimed they use anti-seize. I have used thread sealer with teflon in the past. What do you use? Which way is the best way, if there is one?

I would follow ARP's recommendations. My last 406 I used the teflon paste (first time) and virtually all the lower bolts leaked water. They eventually stopped but it was nerve-racking to say the least. I know I had plenty of sealer and maybe it was a fluke but I won't do it again.

This was also a freshly tanked block so there was no oil to prevent the sealer from getting ahold of the threads (new bolts also).

As jody said use the ARP thread sealer on the head bolts and on the intake bolts (to prevent oil from climbing the threads).

But first you should chase all bolt hole with a bottoming tap and then just prior to installation I spray all of the threads out with Berrymans B-12 carb cleaner to ensure that they are clean and dry.

Never had any leaks using this method.

I have always used "Indian Head" gasket goo and have never had a problem except when cleaning the sicky stuff up. The stuff comes in a little bottle with an applicator that looks like a shoepolish "dauber".IMHO.pdq67

from the things i've been told, a person should NOT use anti seize on any torqued bolt! anti seize will change the ft/lb specs

I have built quite a few motors with aluminum heads and the best thing I have found is felpro gray bolt prep. This is a sealer and a lubricant all in one, so you can use it on all of the head bolts. Never had a leak.

If you check the sheet that comes with the ARP bolts they list different torque specs for their sealer compaired to other sealers. The amount of lubrication from the sealer can change the effort required to turn the bolts which will change the amount of bolt stretch.

I would go with whatever ARP suggests. They are the manufacturer of the hardware and should know what is required to make their fasteners work. The Edelbrock instructions would probably be for someone that is using a replacement fastener that may not come with assembly instructions. Just my $.02!!

Thanks for the suggestions. I guess what has been bothering me was the fact that when I went to a local parts store and had them look up the heads and the bolts in their catalogs. The book claimed that ARP makes Edelbrock head bolts.
What really irritates me is ordering a part like head bolts only to open the package and then find out you should have bought something else. For the price of the ARP bolts, sealant should come with them.
