I've been gathering parts for a while now for the ultimate goal of a m119 powered w111 220b. I now have three m119 engines. A running '92 500sel 119.970 closed deck, short deck (228mm deck height) with 172000 miles, a '95 sl500 119.982 in a parts car but complete never ran with 130xxx ish miles i believe, and i just picked up a 90 or 91 500sl ,119.960 closed deck, tall deck (245mm deck height)with supposedly 4000 miles on it. it had porosity in the deck right near a cylinder and water jacket resulting in a blown headgasket but no milkshake. this thing is spotless inside the heads and timing cover. so i have all the parts i need for the most part and i'll be using the 119.982 for mockup. I'm trying to determine if i can use the 960 tall deck block heads on the 970 closed deck block engine. i found some info saying that they cant be because of different oil and water passage locations, but it listed .970 and .980 together. However i have found that the tall deck .960 and closed deck .970 block use the same headgasket and the later open deck .97x and .98x use a different one. so this would lead me to believe that the passages are the same and that i can use these low mile heads on my good engine. Has anyone tried this combo or have the two heads off an engine to compare? my main concern would be the timing chain guides in the head since the tall deck and short deck blocks guides are totally different in the timing chain cover area on the driver side.
