My suggestion is for you to take the head off yourself, as long as you know how, or have the resources/connections to aquire that information. Since your going to have to have the head inspected for cracks or warping anyways, just take the head bolts with you. You can have the same inspection shop look at those head bolts, while they inspect your head.

Once you get the damage report on your 2.2 head, you can decide if it's worth fixing, or just simply replacing. I used a shop in Portland, OR called Aluminum Head Rebuilders. They were able to pre-load the replacement head with valves, springs, and etc.. This cut down on my rebuild time, which was really nice.

I'm sure there is a similar shop in your area, but if not the above mentioned store does have a website.
