Try and find a shop that is used to working with aluminum OHC cam heads.

When the deck warped so did the journals that the cam runs in.

What I like doing is to heat the head up in an oven and then put them in a press to straighten them. Straigh is as measured along the cam journals.

When the journals are back in line I re-face the head.

This reduces the amount you have to cut and saves line boring the cam journals. A good shop will be able to do this.
