ok , things goes worst .... as I said ... my crank broke .... bought a 302 non Ho ...and I did what my77stangsaid .... was a better idea.... so I took only the crank and sent the rest to the scrapyard.... now the problem : I removed the heads , and the exhaust valve of #6 cylinder is bent ..... I see a gap when the valve is closed ....but I don't see any other gap on ther others valves ..... Is there any trick to know if the oher valves are goods? Do I need to replace them all because I replace one?

Thanks

 

throw the stock heads in the garbage.... now is the best time to do it
