I tested this all out on the work bench last night and it seems like the head will still work like Jerry said in a PM.
I got the domes in and yes they don't just drop in, I had to press them in. So I can see now how bending these tabs happens by getting them misaligned and then bolting on the head.
I had the head in a vise and screwed a spark plug in so I could watch and see if the dome spun. I got the spark plug tight and there never was any rotation.
Shame on me for not reserching this more before I purchased as I would have rather had the new design head. I also should have got more detailed pictures but probably wouldn't have know what to look for anyway since this is my first coolhead. The pictures I saw looked fine.
Shame on the seller for not disclosing this information and calling this a "nice piece". He has yet to return my PM's but it has only been two days so I will give him the benefit of the doubt for now. I would like to get my money back and get Jerry's new design but if I don't at least this one will still work so I didn't get burned too bad.
Thanks for everyones help. Sometimes you should just buy new...
