Head and Block Machined??

[rnoswal]

Almost no head gaskets require any adhesives at all. They are not recommended. If you need clamping power then go with ARP studs. Metal gaskets are usually only for the turbo engines. A FelPro head gasket works just fine in an N/A.

If you do pull the engine, make sure you keep the front aluminum cover on the engine so it can be milled too.

As I said before inanother posting. Don't worry about buying an extra thick headgasket either if it is a N/A engine. The extra compression helps and the cams are easy to retime with the adjuster holes in the cam gears.

The Permatex Brake Quiet also has a high degree of heat resistance. Brake pads get really hot too.
The Permatex Brake Quiet is being used by some of the more experienced guys.
One of those guys put down like 900 HP at Vegas.
From the 4 guys that I know who have used it, they highly recommend it.

From the first statement statement, it implies that so some actually do recommend using a sealant. I was not aware that any manufacturers recommended a sealant at all. I know that Cometic does not.

What is recommended is that the head and the block be milled to a low RA. Some are not taking the block out, in that case, they are not following the manufacturer’s recommendations. If the block is not to be taken out, to get a low RA, then yes, Permatex Brake Quiet will be of great help. Some are even using it whom have had their blocks milled anyways.

Clamping power is not the same as good sealing. Ideally, people should be going with ARP studs anyways, but clamping power will not fix surface irregularities. People do get BHG’s even with lots of clamping power.




All that said, use whatever you fancy.
