Manifold to head gasket - dry or gasket sealer?

[justindaley]

Hi Guys

I'm about to pick up my 2F standard exhaust/inlet manifold from the engineer - surfaces are being trued.

I made a stainless heat shield to replace the standard vent thing from 16g st/steel - seems to work a treat.

I would like some sort of steerage as to whether I should be using the gasket dry or with some gasket sealer.

Also, does anybody know the correct torque values for the nuts/bolts.

After moving house, I've yet to locate my manual.

Thanks for all the help to date.

seal or dry

The advice I have seen seems to always be coat all 4 surfaces and use felpro gaskets if you can or OEM

I double gasket (felpro) along with high-temp silicone between each gasket....
IIRC torque 45 or thereabouts... but I tighten the dog s*** out of them.......

No problems thus-far.......

I run a header on both my F1.5 and my 2F and used no sealer, just OEM + FelPro double gaskets. No leaks on either. Retorquing is the deal breaker, just do it.

Stock manifold and trued your good with single gasket and sealer. Header..double and sealer....and sometimes double on the exhaust and single on intake....worked for me....

X3 on the double gasket (OEM or Felpro) and sealer with a header, unless you had the surfaces planed. You might need to fab some 1/2 washers if you cant get it to seal -
