Head Gasket

[Roland Rodriguez]

Those dings are not good. Check the cylinder walls around the water jacket as they tend to corrode and you will have water intrusion (very typical). Take the heads to a machine shop and have them "shaved" basically grinded straight so they fit nice and tight on the block. New gasket and gasket material a must. I hope this helps but make sure the water has not eaten thru the cylinder sleeve and allowing water to enter.
