For the last 5 days I've had the head filled with 10% vinegar trying to boil out whatever is stopping circulation thru the head. I add a couple of tablespoons of vinegar a day to keep the level to the top of the head. I start it up a couple of times a day and warm it up to help the vinegar do it's thing. Once it got a little cloudy from rust but other than that it has stayed clear. I did get a wire to travel to the back of the head thru the front opening to the goose neck. I feel the openings from the block to the head are stopped up and can't get there to open them up without removing the head. If I remove the head to access, will I have to do valve train work to reinstall the head or will it set back on if I don't turn the engine over? In other words, how much trouble is it to R&R the head gasket with out adjusting the valves? I'm running out of patience with the vinegar.
