My new daily driver. 1984 dodge rampage

I ground out the cracks in my 2.2 turbo head. And had a guy tig weld up the triangle holes. Then i used an old headgasket and lined it up to drill out the center of the welds as a circular hole, then had it decked. Circular hole = no stress concentrations because theres no points for cracks to concentrate at. Now you know why airplane windows have rounded corners lol.
