:worship:worship:worshipyeah they'll fit,but you'll need special 1/2" to 7/16" stepped headbolts
351w uses 1/2" bolts,and the heads will have 1/2" diameter bolt holes drrilled thru
302 uses 7/16" bolts
also,just cuz they're on a 351 doesnt mean they're any better than the E7's from your 302..what heads are they?
It's not a 335-series motor (Cleveland), the last year for those was '75. Do your research well before investing any time or money into them. I don't recall ever hearing of any good heads produced in the '80s.They appear to be the stock heads from the 84 351. I had read this is basically the boss 302 set up. If you're asking if they're windsor or cleveland I don't think i can tell utill I take them off. Not sure what they offered in 84.
