Stop in for a cup of coffee

No drugs, no weed. I find my relaxation hitting golf balls.
I can go to the range and hit balls or putt for hours and find my happy place.
Same with going to the range - can be pretty relaxing - depending on what your doing and what your shooting.
Wel the bird is back hitting the windows. Stupid bird. The wife is loosing it! Do they make retard helmets for birds?
Try some bird siloutes on the outside of the glass.
What will take this gasket residue off?

A snap lock disk or what I like is a flat honing stone for a knife about 6" long.

No scuff disks here on mating surfaces.
I learned my lesson the hard way. Too long a story to post now.
Just say no.
Just the passenger side. Which didn't have a gasket on the exhaust manifold either. Related maybe?
No gaskets were used on exhaust manifolds, just the heat shields when needed.
The surfaces are flat and seal metal to metal.
I've lapped exhaust manifolds but never heads. That would take a big surface - like a granite block made for lapping - and some skill and expeirence so as to not do the edges more than the middle.
