[hot rod heep]

witch heads are going to  be better for  a 496 bbc    088   or 049 s  both   are iaron and  have had some porting done   the 088s are recktangle ports and the 049s  are ovels

rec. ports are better for higher rpms... 049s are closed chamber and are good for lower and mid.. but more of a street engine... ive been trying to find some good original heads for my 402 bbc im building for my 79 camaro, and everybody is recommending the 049s
