Stock 862 head castings Does anyone know the stock flow numbers on these, chamber size, runner volume, etc etc???
I have the 706 castings now on my 5.3 motor and will be swapping these out if its worth it. Not until after I have them worked of course
Just wondering if they were going to be better in stock form to begin with than what I have already....
Fill me in guys. Thanks
