The head on my parents EBII 4 litre appears to be warped. He has been told that machining will not be suitable so you either have to buy a reco head, or a brand new one from Ford. Is there anywhere that sells performance heads for the 6 at a reasonable price? If now what's the best option $470 for a reco one, or $710 for a brand new one from Ford?

Apparantly its warped or something, it is possible to machine it, but he was told that its better to reco or buy another one. I don't really know much about these engines by the way :)

If its warped they have to straighten it first, before machining.

I have recently bought a 323 and it had a warped head(alloy), it was warped 3mm in the middle, the head is only 18inches long. Thats a big bend.
They heated it in spots with the Oxy tourch and the head sort of just poped back straight, then they only had to machine 1/4 of a mm of.
It cost me $200 for thestraighten and recon.

im a cylinder head reconditioner in mackay qld .falcon heads can be warped up to .020 thou before having to straighten them as they dont have a cam cap that is of bearing clearance.but if they are bent the valves and seats run out of concentricity and leak as a result.i recoed mine and ported it and it goes like a shower of shit now and i didnt even do that much to it.i would recommend reco as long as the head isnt soft.MAKE SURE THEY TEST IT FIRST !!. as u can end up with a reco head that is softer after straightning as heat is involved (spot heating)and this will cause gasket failure down the track.if u have any questions about it ill be quite happy to tell u more.
