Reply to "Type IV Complete Engine for Sale"

I just looked up an article about the type 4 head types and it said the 2.0 heads unique to the 914 and the 76/912 had valve sizes of 42/36 not 38. Portion of article below:

When Porsche introduced the 2.0L Type 4 engine in 1973, it featured a unique head design that was only used on 2.0 914/4s and the 1976 912E. This cylinder head features a unique spark plug location, the largest valve combination (42mm intake, 36mm exhaust), and a unique combustion chamber shape. The quickest and easiest way to distinguish a 914/912E 2.0 head is by the three intake manifold studs; all other Type 4 heads had 4 intake studs. These studs are readily visible in both of these pictures. Another item to note is the angle of the spark plug and how it differs from the other Type 4 heads.

My heads have 4 intake manifold studs and I was told the heads are 1.8 heads that were reworked by Jake Raby. Thus the larger valves and the porting work.
