welding MC 5 cylinder exhaust manifold?

[Kurt Deschler]

Both of my 10V EMs are TIG welded and holding up very well. You need to 
find a competant welder who will prep and pre-heat the EM correctly and 
have it surfaced afterwards. I know a good welder/machine shop in the 
Fitchburg MA area if you are near that area. Common 3/8" studs from the HW 
store work well to replace the crap 8mm stock ones that break off when you 
remove the EM.
