Some pics of my manifold:

Four pretty good cracks, I have the new here along with MLS gaskets, and all drilled out already :)

Scott is that your first one like that. I have 3 like that under my work bench. I decided with this last one im going to keep welding it up. Sick of buying new ones so i been grinding out the cracks and welding the up. so far its working.
 
Looks like mine, I welded mine up and it cracked again after a while it has been on the truck since 02, think I'll try a PDI next time.

This manifold has been on the truck (pulling Truck :) ) for three seasons just kept getting worse and this season it was a pain to clean up the mess as it got progressivly worse. I don't think when we drill eight holes in them for sensors that it helps any, and I can't imagine how fast it would crack if it were ported like some I have seen.

Jim isn't the PDI pretty much the same? is it a different material? perhaps they can let me test one for them :)

I think there about the same, the ATS T-4 that I bought a few months back is ported with a machine a little more and I smoothed it from there.

why not make a custom header for it?
 
I use to have this problem with the one on my 12V. I drilled the holes and put some taper plugs in under pressure in the T/C holes I was going to use and then METALAXed the thing. No more problem. It's the stesses that are inside it after the casting process that makes it fracture. It's working against it self as soon as it come out. CRYO dosen't do the same thing. In CRYO it can move after the process. In METALAX it doesn't move at all after treatment. You get a sheet that shows the stresses in it before and after treatment. I have a machine here to do it. This is a process that should be done to all motor components. It helps them live. No stresses working against itself in there.

Any chance we can get ATS to spring for it? Since there manifolds seem to have some serious durability problems?
