Worth welding chambers I have a set of 317 heads and only want to run them if I can weld the chambers then mill the minimum just to true them up. These heads will be ported and put on a 5.3 Single turbo setup, with a set of ls9 head gaskets on 92-93 octane. I know there are other head options out there, but I could get them welded and milled for probably half the cost of better stock heads that are used. The questions I have are...
Where to weld in the chamber?
How much will the head distort if done by a highly experienced welder?
How many cc of weld should be put in the chamber ?
I was thinking of welding between the deck and plug hole with a total of 4cc welding material which should close the chamber down to 66cc. Then milling a little .007-.014 will lower it down to 63-64cc if all goes well.
All inputs are appreciated.

After talking to a machine shop that knows heads, he said just mill them down as I will not see any difference being a street car 99% of the time. He also said the minimal amount of valve shroud won't effect the performance I am looking for. Now if I were to make this a drag only engine where every .001 counts then that's a different story.
