Instead of wasting money on gasket sealers . my advice would be to buy something similar to ;

NOTE THE FOLLOWING ADDITIONAL INFO FROM RELIANT ;

My CommentsRemember when torquing to start at 5 lb/ft then 10 then 15 then 20 and finally 25 { remembering to only torque studs 11 and 12 to 20 lb/ft
I personally would not back the nut of half a turn and I only do 1/8 turn .
*If you torque the cylinder head then wait till you have done the recommended 500 miles , chances are that you will develop head gasket problems !
The gasket will have compressed /bedded in after the first heat up / cool down cycle .
After the first heat up / cool down cycle as above , let it lie dormant for 8 hours or so and then whip the rocker cover off and the rocker shaft and retorque .
Run it back up to hot again and let it cool down .
Let it lie dormant for another 8 hours or so and then whip the rocker cover off and the rocker shaft and retorque .
Run it back up to hot again and let it cool down .
Should be ready for many trouble free head gasket miles .
