Yeah, we've fixed a number of subie heads with serious pitting (in fact
chunks missing at times), best way is definately TIG, we've had great
results. As in the subies, it's a good idea to check with a multimeter to
see that your cooling system isn't charged(one probe in the expansion tank,
one on the battery neg) as this is a fast way to corrode parts quickly.
I've seen a brand new heater core leak in a month of use because the system
was going through electrolysis so badly. Never a bad idea to run a few
extra grounds to both the block and your heater cores to prevent this.
