I have been working on porting my own cylinder head based on David Vizard's bible and unfortunately I ground a bit more than I should have near the exhaust port of the combustion chamber and now I risk head gasket failure if I don't address this issue.
I have a MIG welder can I use that to build up the chamber a bit and then re-shape it without overdoing it this time?
If yes will a standard steel wire do or do I need something special?
Thanks,
Nik
