So after deciding to put a h22 head on the f22, I pulled the head off the car today and saw this.Can you tell me if my sleeves are ok and what would cause the burn marks? I took pics of the worst 2. Heres a few pics. . Btw- the block has 9k miles on it since the build. And I can move the pistons about an 1/8 of an inch around the cylinder. I did a compression check before tearing down the motor. All was ok, ranging from 207-210 across. All input is welcome.
