Exactly.

I had a bad HG on mine, just like yours. Clean oil, no issues, but when I would floor it coolant would puke all over from the overflow tube. Ugh what a mess.

My HG issue (sounds like your too) is that combustion gasses are passing thru into the water jackets, pushing all coolant out. 15 psi of coolant pressure is going to lose agaisnt the 150 psi of combustion in whichever chamber the HG passage is cracked.

Not an easy fix, not a difficult one either. Just pick up a MLS gasket from Ben at WOT-Tech and new head bolts and do it.
