7M head cross section

[amichie]

Did anybody ever take a head cross section through ports.

Like the picture in this link of a 4AGE head.

The one on IJ's thread is through the centre and doesn't really show the ports. I am particularly interested in the shape around the valve guide.

Toyota did. And they have drawings in the repair manual in the first section, which is an introduction.

The drawing probably doesn't have the detail you want.

Is this any help?

Yes.

The bit around the valve guide seems to be the most restrictive. It also seems to have heaps of meat underneath for a bit of opening up etc.

IJ. cut one up. I'm sure he's got pics somewhere. Search under his name: IJ. <-- make sure to put the period after his name.
