Is it possible to check a cylinder head is flat, DIY?

[Martin#30]

Due to a monumentally siezed exhuast stud, a complete failure by Plusgas, heat and bolt extractrors, I had to break out the drill to try and remove a snapped, and stuck exhaust stud.

3 evenings of very careful drilling later, I have managed to drill though the head into the water passage . Muppet 

Second hand cylinder head is winging its way to me, but I want to be sure it is completely flat before fitting. Is it possible to do it DIY - maybe I can buy a flat plane something, or is it realistically machine shop only?

To check something is flat you have to do it with something flat...for the tolerances your dealing with an Engineering shop is the only place.

You really need a Coordinate measuring machine (CMM), a mill and a Dial Test Indicator, or a surface table with a DTI again. Where are you ?

Where are you ?

Betwixt Bristol and Swindon. I have been pointed towards an engineering firm called Piston Broke in Bristol. I have used Tim Radley a few times before in Gloucester too, I imagine he has the gear to do this also.

As it is only a simple check and confirmation of 'flatness' I need, I am hoping to find someone local-ish who would be happy to check it whilst I wait.

I could check it in (after) work one afternoon if you can get it to Bishops Cleeve.

Ash,

That is a very kind offer, thank you. I am waiting on a call back from a local place, but if that proves no good, I will PM you and see if your offer still stands.

Tim Radley at Race Developments in your neck of the woods will do this for you ...
