Just a quick note. I have used BG44 before. It does a great job cleaning carbon and junk. If ya pour a bit on a piston head fulll of gunk, it will be clean in 5 mins. Ran it in my 79 blazer 350 and you could eat off the inside after. Ran great after use.

Where are you getting the 44 from? I havent seen it in years. Good luck with your engine man... my fingers are crossed for ya.
