Any clues as to engine size? Options

[Tdskip]

Hi guys-hope everybody's having a good day. I was fortunate off to get a ton of help from Forest and Keith today getting the "turbo" clutch issue sorted out. I can't say enough about how helpful they were and gracious with their time.

One of the things that I suspected, but it appears we now have proof of, is that this engine was built up from the original 2.0 GC case spec.

Can anyone identify these heads or help make a guess as to displaceme

You can't tell engine displacement from pictures of the heads.
If you had the right pictures someone could ID the heads but that doesn't really tell you much.

Anyone could use any heads (1.7, 1.8 or 2.0) to build any size engine.

For 914 heads, 1.7 & 1.8 heads have 4 intake studs and 2.0 heads have 3 intake studs.
On 1.7 & 1.8 heads the spark plug holes are angled up more than 2.0 heads.
Those are the prominent visual differences between the heads.

Pistons and crank are what change the displacement and you can't see them with the engine assembled.

If you have a GC case and 3 stud heads you probably have a 2.0 engine at least.

It is common to put bigger pistons and cylinders on as part of a rebuild, so who knows what is under the cylinder head.
