Cylinder head/manifold erosion

   Okay, thanks guys.  I was considering just milling up a 'sleeve/wedge' to put in there for now (rather than yanking the head)... but I'll wait 'till after I've fired it up to decide on my plan of action. I do have another head here of unknown condition- I'll give it a thorough look-over and see if it's in appropriate condition for a swap.

I assume that if they planed 'em, that there was a fair amount of 'meat' in that casting?

	I have had the heads brazed up and then planned down. Not the best situation, but gets a little more out of a good head.

	Dave, that might be alot to be milled off, but I had that done on a WC head once that was quite eroded and it worked out fine.

	Hi everybody! So I'm working on a WD engine, and the #1 exhaust port surface is about 0.050" eroded on the HEAD side... the manifold looks flat, but the head is eroded away. Obviously, the best answer is to stick a different head on it... but... has anyone attempted other methods of solving this problem? My D17 had MANIFOLD erosion around the #3E port, so I set it up in the Bridgeport and milled it off 'till flat, and it's been happy ever since. I don't think I wanna put that head in the mill and chew off that much iron... mebbie cut a sleeve that'll fit inside the port, and inside the manifold?
