Re: ZL-1 & L-88 head design clarification
The L-88's all were aluminum heads from the factory. The 69 switch over from the 842 closed chamber design to the 074 open chamber design was around serial # 21,000 (if my memory serves me well) But as a side not the L-89's did not change to the 074 they were all 842. Hope this helps, Rich.
