I am restoring the 1973 914 my dad had when I was growing up. It has a 1.7L motor. I know I will need 2.0 liter heads. What do you recommend. There is a great price variance. I assume I will also need 2.0 headers among other things.

If you were to use 2.0 heads, then you would also need the 2.0 tin over the engine since the spark plugs are located differently; 2.0 tin is hard to find now. It also may be easier to find intake manifolds for the 4 stud 1.7/1.8 heads; 2.0 heads have significantly different manifold mounting. The 914 2.0 heads are uniquely Porsche; bus parts are not the same.

Thanks for the info. I know about the tins. The spark plug holes are in a different place. I saw a guy online who sells a template to redrill 1.7 tins to match up.
