So can the 6.4 heads work on a 5.7 bore? Even with say a .020" overbore? If so, I am going to pull the trigger on those heads that sixpackgut mentioned...wondering if they are bare or complete heads for that price also.




Based on info from this read I would say no.. read it

I read that already...but I am wondering if with an overbore a 5.7 can use those heads? Although I am thinking no as well since there is a .170" difference in bore size between the 2 engines.
