JB weld and 4.0 head swap=rust?

I plugged my water jackets with JB Weld or Kwik Steel, I can't remember now. I removed my radiator line and this is what I found. It is like a rusty gritty material. It is somewhat sticks to a magnet. I'm thinking that JB weld that I used to plug the coolant passages is rusting and creating this? Anyone else with experience? I know everyone is using this stuff so I hope someone else can either confirm or deny this issue?

I used quik steel on mine I stuffed disolving foam packing peanuts in then the expoy on top. I think your problem is completely unrelated did you use distilled water when you filled your cooling system back up when you did the swap? I have been running my 4.0 head for 3.5 years now and I love it.

I did use distiller water. I also found heavy rust sediment in my block too. I m glad to hear others are not having this problem. I guess I'll flush it all out and start new.

I've been running mine for about a year with jb weld and nothing like that yet. You could try asking in the cj forum I know a lot of them are running that setup maybe you could get some more opinions.
