I also have an 8BA flathead V8 that is complete. I pulled the heads to check for cracks and could not find any. I used 400 grit in between the valves and cylinder walls where they like to crack but did not see anything. It is not stuck. It is standard bore. It had clean oil in it. It came out of a 1950 truck. I have an extra set of heads and an extra crank for it. It needs to go. I also have a 226 flat 6 block and a 215 6 that is stuck. MAKE ME AN OFFER!!!
