i found an add on craigs for 351 heads mill ported polished with a set of svo motorsport 1.6 roller rockers and arp bolts 300b/o will these fit on my 302? i kno some parts are interchangable but im not sure thanx. and will this give any performance increase?

if they are true 351 heads you'll need to use spacers/ reducers as 351 heads had 1/2 heads bolts vs 302 7/16 and they probably don't have smog provisions either as far as performance increas..it'll depend on cumbustion chamber size and the size valves in the heads already..if it's just stock...probably not enough benifit to out weigh the hassle of all the work required to do the swap
