This happened a couple years ago but it's always bothered me.
I pulled a head on my buick and found cracks between the valves so I replaced them. The head gasket didn't take on the front cylinder bank. I cleaned the bolt holes, used copper spray a gasket and took extra care to line up the dowel pins and gently place the heads on the gasket. Even torqued the head bolts to 37 lb ft plus 120 degrees.
After firing it up and test driving it I noticed a substantial loss in power. I pulled the front head and found a lot of coolant in cylinder number 5. The rear cylinder bank sealed right up without any issues.
What could of caused that to happen?
