I defintiely decided to go with new brass plugs. Trying to get the block cleaned and painted now. Our temps dropped today so it was too cold to paint what I have prepped.

Put all new brass freeze plugs in. Got the replacement motor back in and it runs great. Oil pressure is 40+ at warm idle. no leaks so far from any freeze plug. Hope this motor is good for another 100k miles. It think this is the only pic have of the new brass freeze plugs. I thought I had one of the back, but I'm not seeing it. Got the motor back in and everything is running great. I got 8 plugs from Napa, but only 7 are needed since 1 is for the cam shaft.
