I know I can buy these plugs from a vendor but does anybody know what size bolts I can fit into the back of the cylinder heads to plug the egr ports? I will remove the tubes but behind them is threads that screw into the head.

5/8-11 x1" bolts with 2 washers.

2 washers because the holes are slightly deeper than 3/4" before you hit the inside of part of the casting... the washer helps space them out slightly.
