where did the 351 come from?? did u just get it from a wrecking yard and drop it in?? might have alot of miles on it.
when does the smoke come out?? when driving? when you first start and then it stops? don't waste your time on stock 302 heads on a 351. by the time you get them rebuilt and ported and ploished you could buy a good set of iron head or maybe even aluminums.
