Sorry to sound ignorant, but which cars use the B18A1 or B1 engine? I've been looking around at salvage yards for 91 integra's, but I know other cars will work. If I had a year range and car model to look for it will be very helpful.

BTW, the car is my wife's. She claims she might have been accelerating when it broke, maybe going 3K or so while changing from 3rd to 4th gear. Anyway, how can I tell if the head is usable or in bad shape? Will I be able to tell if the valves are bent?

Also, thanks again for your replies. They are very helpful.
