Does the uni have ultrasound, xray or MRI? There are plenty of non-destructive methods of measuring sections. You can get a good outer surface with a laser scanner or LIDAR. If you can get the scan in a point cloud then you can convert it to a CAD model.

The best thing about this approach is you an scan a few heads, get an idea of deviation in the casting without destroying anything. Maybe have a talk to the Metrology people at the university before cutting it up, see what they have.

I sliced many vw heads with a "drop saw" but with it standing up like a normal bandsaw, you only need a little platform to support the material.

Hey old fart,

That sounds like a good plan. I could post the head to you and you could cut it along with the A12 heads and re-send (postage on me). You'd get the AutoCad drawings first.

I have access to the workshop at uni but at the moment things are quiet so it's hard to sneak work in.

PM me if you want to go ahead with this?

Chris

A wood band saw will cut it ok.Metal better but reasonably hi speed ok.
Skip tooth blade best.Remove the valve guides esp if using a wood saw.
I have some cutting grease I used to apply when cutting a lot of Al so it wouldn't pick up on the blade.
If you are stuck I can do it for you at work.(Civil Eng. Sydney Uni)
I have a few old a12 heads I plan to do similar to re a crossflow design.
