High spot on engine block
The block is in the car and I have no intention of pulling it. Is there a method to rub it down? Sent from my iPad using Tapatalk |

I'm sure there is a method to achieve what you want like using a knife sharpening stone. I would search YouTube for examples. Probably use some blue dye to determine progress.
I would probably secure some thin metal shim on the sides of the high spirits and use a stone to shave it down to the level of the shims then remove the shims to finish the job. Just an educated guess of what would be done. I would try to find some YouTube videos first.

I don't know how that could happen since the block is faced when built. I would set the head on the block without the gasket and verify there is a gap with feeler gauges or use a dial gauge to measure how bad it is. Might correct the problem if there is a thicker head gasket available. If it needs to be corrected I would have it done by a professional. If you go too far it will be a much bigger issue. Was there always a problem with the head gasket or was it OK at one time?

Don’t know the answer, when I acquired it the gasket was bad. I’m going to re-examine it later today, hoping it was mostly my imagination. I will be installing a 1.0 mm headgasket when the weather warms up.

How it got there? I would suspect corrosion from interaction with the coolant or oil that was leaking through the gasket. Aluminum will definitely swell when corrosion takes root.
The concern is: if you try to remove the bump will you create a pit? Is the bump basically a big flake about to peel off and leave a big hole?

I should take a closer look before I post. Needs to be about 10 degrees warmer and damned if it’s not sprinkling rain again. Sent from my iPad using Tapatalk |

You should get a dial indicator on it and find out just how tall the bump is. You may be able to feel it, but I've found fingers can be quite sensitive to small height differences depending on conditions. It may feel worse than it really is.

Hopefully it's not a plug that was used to repair a crack.
