What Ken has said about the hi-comp & lo-comp heads is correct. But, you will find that an original 149 head & an original 161 head are near identical, their combustion chambers are the same small kidney shaped item. As a matter of fact the early 161 heads have the same casting number. So, to answer your question it will fit & nothing will change. AFAIK the only change was the addition of the extra small water outlet hole, at the front of the head to suit the 161's 3-bolt thermostat housing to suit the water heated manifold hoses. The 149 had no water hole there & only 2 of the bolt holes were used. Dr Terry. Title: Re: heads Post by: fe-ute56 on October 30, 2005, 11:32:19 AM Thanks Terry thats what I wanted to hear
