Well, lets see what is involved? Head gaskets ~$90, intake gasket $30, oil and filter, possible pan gasket. If all goes well, labor about 6 hours not including re-torque, Local shops run from $60-80 per hour. With a blow into the water passage the pan must be removed and all oil passages flushed then also figure a case of oil and R&R the cam sensor.
Hey,
If you blow a head-gasket, try to replace it yourself to save money. It may seem hard, but, if you have any mechanical skills you could do it. If you dont trust yourself, then dont do it. Honestly, its not that hard. Ive done it enough to be able to do the complete job on both heads in a day. Just takes patience at first but, when you think of all the money youve saved, you could buy some speed parts with it instead!! Good luck and I hope you dont ever blow them!

Wow thats quick.
Book time for the head gaskets in my van was like 16 hours
Needless to say a friend and I did the work, not the shop.
I hope I dont have to do the Regal's anytime soon...
