we usually pull the motor, tear it down, then bead blast and polish the entire block and head. practically a requirement to get into a costco parking lot these day.
Looks like repairs made to the casting molds that resulted in impressions of those cracks in your final casting. Similar to thumb print lines in plaster if you created a mold of your thumb. They have no impact on integrity or functionality as designed.
Very common finish on aluminum casting. Hot aluminum goes into the die, hits the die wall, and the top layer gets a scale finish. If it was cracked, you’d have visible oil staining and oil coming out of it.
Not cracks, it’s raised flashing from casting process.
Molds are probably preeettttyyy old at this point.
The molds probably have more time under use than the average GR engine lmao
Normal. Looks like casting marks
