In the back of the afr catolog it has a 302 setup with 185,Comp Cam with 565/574 232/[email protected] with 1.6 roller rockers 112lobe sep,10:1 comp,650 speed demon,1 3/4 headers,Victor Jr intake and said made peak 455 hp and 398tq. My ? is would these heads be to big for my 289(.030 over)11:1 comp,Lunati cam with .508 lift(not sure other specs...misplaced cam card),1.6 roller rockersWeiand Stealth intake and (hopefully bigs)or Speed Demon 650? I saw the 165 but might put a 351 in the future(few years) as this is everyday driven and i would hate to but some heads only to have to replace them in a few years. Thanks for your help.
