350 SBC?
 

chevy sbc 350? Can anyone tell me how to identify on how to tell what heads i have by the casting numbers?The block is a 880 which i think is 1996-2002.It has a roller cam and lifters, 2 bolt mains. I bought this motor to build for a boat i'm building. Could this engine have Vortex heads? The only thing i'm sure of that the valve cover bolts has 4 going right down the center. Thanks newbie!!

take valve cover off should have casting numbers on heads.
