They are an "over the counter head" . Out of the box , they flow more than any of the double hump head's , as well as the 041 , 041X , 461 , 461X , 462 , and less than the Vortec and Bowtie . If your not allowed to run the Vortec , Bowtie or aftermarket head's , then they are the best that you can use . But must be VERY selective in choosing a good set of 492 head's !!! Since they are "Hencho in Mexico" , it is difficult to find a good set with no core shift or casting flaw's .

492's are double humps.They came on several hipo engines in yhe late 70's-early 80's.They are available as a service replacement for early double humps.Current versions have 64cc. chambers,2.02intakes & 1.6Exhausts and are set up for ***** -in studs.
