-------No, Rick,,,All 188 of them had aluminum heads. There were a few automatics as well as M21s and M22s. As well, there were a few ZR2s which had even more similarities to an L88. If you wanted the baddest 71 Corvette you could get, you ordered LS6 and ZR2 along with a few other HD options. I think you had to order them both, but Warren would know for sure!!! The silver LS6 I owned while I lived in Chicago had 355s and was good for 160mph easily. What a top end machine that was.........Bill S
