So I was tightening up my header blots and snapped on off
on the driver side first port front bolt. While trying to drill and tap a new hole, I accidentally drilled off to the right. A couple drips of anti freeze can out. I did get the hole tapped, put a bunch of thread sealant in there and its holding for now. What should I do about new heads? just replace the one or upgrade them both? What are my options? Pricing? and where to look? any help is greatly appreciated!
