Headgaskets Aluminum Heads

I've never used a sealer, I was taught by my grandfather and dad to retorque the top end.
Never had a problem by doing so.
I even use an inch pound torque wrench on the tins. lol
Broke in cams years ago with wheel bearing grease. lol
Never a flat lobe. I guess I was lucky, many here are not.:D
I use an inch pound on the tin stuff with cork gaskets for obvious reasons as well. The cork can usually do with a re-torque down the track.
Cometics come with a coating already on them, so it's beyond me why you would coat them.
Back in the day some production engines required re-torquing at various service intervals, but the "monotorque" style gasket put an end to that.
It's pretty obvious by this thread that people don't understand why differnt styles of gaskets are made and what thier aplications are designed for, also how to use them correctly.
