Head gasket prep 16v
Forgive my ignorance but working on this engine has me paranoid beyond the norm
These head gasket surfaces are a bear to clean. I am using some professional carb cleaner and a fine 3m abrasive pad by hand. Am I correct in my approach. Seems to be slow and tedious and I am starting to question how clean this aluminum needs to be.
Have done many ls series GM engines but they are newer and the gaskets seem to come off cleaner due to less age.
Feedback? Thanks!

I would put the scotchbrite away,
go buy a fresh pack of good razor blades and change then regularly
Hold the bade perpendicular to the surface and scratch back and forth.
Use a straight edge to see if the bores are flush with the sides of the block
if not flush then decking should be performed.

I love green scotchbrite scrubby pads for this kind of thing.
They aren't aggressive or abrasive, just scrubby...
Light hand pressure and a little bit of oil or brake cleaner will go a long way to make the surface nice and clean.

Be careful not to take off too much material in one spot by scrubbing it like a mad man. The deck and head surface need to be flat and uniform. If you get to a point that aluminium has to be scrubbed away to get to the corroded/pitted sections, than you either stop and use the parts as is or have them re surfaced at a machine shop.
