Need a casting number - as there are several different ones. Any screw-in rocker stud head will go for $200 to $500 on ebay depending on how lucky you get. ALL 1969 screw-in stud 400 heads are too high of compression for pump gas, but they make ok cheap drag race power, and take well to good porting. Look on top of the center two exhaust ports for a cast in number. Like a 1 and a 6, or a 6 and a 2. Put those two together and you have the number Pontiac guys i.d. the heads by.
