Still worried about welding just being too hot and there being a danger of warping the head. Hoping to hear that this is not a big risk if I take it easy from someone that has been through this with an M96 engine. Have you, Iceman?

I have found quite a lot on the net of people drilling out with jigs on M96, but not much about the weld method. Wondering why.

not on an M96 engine. but given the heat an exhaust manifold puts out . i wouldn't hesitate to do it , but i get it, everyone's risk tolerance is different.

good advice above.
