scottie- actually one of my spark plugs did break off in the number 3 cylinder if you look you can see an indentation from where the tip broke off but honestly the plugs never looked bad.
Dj sunrise- TIG welding with 4043 filler wire. my machine shop told me to clean it and go ahead and weld it. He said its not that big of a deal. That head is has a great cast very little contaminants it welded perfect. After welding this i would be confident welding on another head anyday.
Rubberbiscuitt- Preheat, fuck it. i know preheat helps in some cases ive dealt with but typically i dont. im sure people will have something to say about that but whatever. After its machined down there will be very little filler left in the head.
