Removing 340 heads

Two more tips; 1) if you drain the block,both sides, you don't get near the amount of coolant into the cylinders.

Or in the pan which might be more important

Instead of prying in the coolant ports, you can pry underneath, going across the chinawall. Or whatever works for you.

Preferably using a hard clean 2x4 or rag protected bar
