Head identification
I have a remanufactured engine in my '91 RS. How would I go about identifying the type of head, rockers in it.
I'm not afraid to pull the valve covers to look around.

Not much identifying to do with rockers... just look at them.
The casting number is on the head surface in the rocker gallery, it will be a 6, 7 or 8 digit number. Look it up at www.mortec.com
