You will like those heads alot. I did the same thing ordering those same heads through Porter and letting him clean them up and then send them to me. On my old 64 I had that 493 running 9.80's and had to slow it down because of no cage
Now I have a set of the big EZ's because the 63 is about 400lbs heavier then the old car and it has gotten me into the 9.60's.
Kees us updated on the progress and outome once it's up and running.
