You're obviously past the drilling out the heads point, but man, I'd never even attempt one hole in cast iron, much less both heads worth. Mine were done by a machine shop and I still had a time getting the bolts all started by hand. Seemed like the last one just wouldn't start, even though visually it looked perfectly aligned. Did you end up drilling them all out or did you surrender to a machine shop?
