Tony's right, way too hot for the epoxy which I've heard works for intakes. I
did a lot of welding to my exhaust valve pockets and its a pretty big
commitment even if your the one that's going to grind it all back out.
Just finding a shop that's qualified to do the welding is a big challenge.
I got lucky and found one right here in Denver. I cut sections from a stock
head and clayed in where I wanted the weld so they had a clear guide to work
from. You can see pictures of those sections on TerriAnns site.
I have other pix of the clay work, the welding and the final product if you
choose to go that way.
