I am new to the Pontiac Firebird forum and this is my very first post. I recently inherited a 69 Pontiac Firebird with a 350 V8 from my father after it sat for over 25 years. I have pulled the motor from the vehicle and I have been tearing it down. I got down to the engine block and I noticed that there are several holes that appear to be blocked? I believe these are coolant holes. I have attached a picture if anyone is able to tell me if this is normal or if I need to drill these holes out? Thank you for all of your help![img]https://firstgenfirebird.org/forums...umber/21075/filename/20251024_171351.jpg[/img]
