Do I need to use some kind of sealant or anything between them and the block and/or heads?

No,install them dry and make sure things are very clean and grease free.

Anthony is correct. I highly recommend you retorque after first heat up cool down cycle if using not stock fasteners.

I spray both sides of the gasket with permatex copper spray and torque to 80 lb-ft with arp studs.

Installed mine dry and used ARP bolts and torqued them to spec with no problems. I agree make sure you have a good clean surface before you start. I wanted to use the copper spray but Tony at AFR told me to put them on dry so I did.

I used a small film of copper gasket spray as well. No problems whatsoever here. I've heard of more problems without the copper gasket than with.

My engine builder went dry, but question:

How many of you guys with ARP's had to go back and retorque after the first heat cycle?

Thanks. Firing up the new motor Saturday.

I fired up my Darton wet sleeved 427 yesterday and have a water leak at the bottom of the head at #3 cylinder. Used ARP studs torqued to 65/fps as told by Cartek and used the Cometic gaskets. Darton has said a leak can be common and that alot of people use the copper gasket spray. My leak has stopped so far today but I think I will torque them down alittle more when I readjust the valves. I'll use the spray if i still have the leak later. By the way, can this Cometic gaskets be reused/retorqued?

Cometics can be reused. Follow their instructions if you do so.

There's no reason not to use the copper gasket spray.

Where can you pick the spray up at?

I have resued mine three times. I have never used and sealant.

Any parts store should have it. It's made by Permatex. I believe it's in a copper colored can and titled "copper spray gasket" or something of the likes. You can't miss it.
