thanks for the info. just got in form working on my engine and i found what you described. did you use brass plugs for the discs on the ends?
I'm disappointed because the MFG description says all plugs in water jacket are brass which obviously is not true. on one had i wanted the brass but at the same time it's not likely to ever be a problem in my lifetime if i use steel i wouldn't think...
my side plugs don't seem that bad but I'm thinking i will still replace since the engine is stripped. opinion?
