Block prep question for head gasket replacement.



Doing head gaskets in my truck and want to know if this is good enough to drop the head onto or if I need to keep cleaning.

That would be good enough for me, I don't have pictures but when I did head gaskets on my LB7 the block looked comparable to that when I put it back together.

Yea pretty well as long as you can't feel anything with your fingernails.
Hope you didn't use the brown Scotch Brite pads.

Nope, did not use a scotch brite pad. My fingernail didn’t get caught on anything either.
