Re: [Chrysler300] 413 Welch plugs



I think to do this right you have to machine the block to remove the lip the flat stock discs sit on . Just putting GM style cups in the holes does not work correctly . They need to go in flush all the way . Maybe you did this machining? If not they will not grab as designed .precision size of hole too ? 
I am a big believer in the hot heads aluminum plugs held with a stainless steel bolt and toggle bolt like strap . This cannot come out . The bolts from hot heads are slightly too short aggravating putting them in , unbelievably so , inside parts can drop into water jacket . You are done for . I had a bare block got the toggle bar out of top of block. Get 1/4 longer bolts . Made for 392 , may be same size as B , and a bolt in . The o ring  sits on the block lip. Which must be clean .  lost a disc one on first trip on 392 ,huge hassle you get 2 minutes to boiling in head.  very tricky to get in right with stock , but stock works. A skill issue . No one does this in 2017, they do not have the experience . But stock rusts too . On heads maybe cups are a good answer ? Machining them anyway at a rebuild. 
Bottom line hot heads bolt in plugs end this problem on block.  And can be done without machining . Need to check if 413?and 392 same size . A good machinist can make this too . John G
