Im sure you heard me crying last week about the first machine shop i went to and how the royally screwed me over. So I took them to my other machine shop and they charged 1/3 less $ and did 50% more work. So I get my heads back and im so [] happy. When I get them home I notice that the first shop stripped the Steam line bolt hole threads. I thought my issues w/ them were over but, they found away to [] me again. $60 for some douchebags to [] my heads, and thats all they did.

Ive read here that guys are using AN fittings or Helicoil to repair this problem. Please let me know what size fittings or coil will work. Thankyou.

 

how bad are they stripped, sometimes you can get away with just rethreading them

 

Their gone, ive got tons of AN's laying around mostly from Fuel lines. etc...

 

I had the same problem with my TF heads. I strippedthem after the motor was in the car...

Fortunately I had a spare set of heads laying around. Here is what I did to fix the problem fairly easily.

I went to home depot abd bought a piece of 1/8" thick aluminum plate. (to make a template since aluminum is easier to work with.) Notice just above and below the steam pipe hole there are 2 3/8" bolt hole. I made a plate similar to an EGR block off plate and bolted it to the head to cover the steam hole. now I found dead center of the steam pipe hole and drilled a hole in the plate. Now I transfered all of these measurements to a 5/16" or 1/4" thick steel plate and made the same plate from steel. Drilled and tapped the hole in the center for the steam pipe. I made a gasket to go between the plate and the head and bolted it to the heads. now I bolted the steam pipe to the new plates and away I go.

I made the plate from steel because it wont strip out as easily as aluminum.

Your only other route is to have the hole welded and retapped. Any machine shop can do the repair but i found my way much easier. But I have all teh tools to do this kind of thing and I am pretty good with small fabrication work.
