casting# rear is 6 front 5 should be same#? whats the difference between 6 and 5 ? s-l16002.jpg

I am assuming that these are aluminum. The 5 I believe is a low compression head commonly found on WLA's. You should be able to see the difference in the deck height. Jerry

thanks Jerry, so they should be the same#

[Jerry Wieland]

Yes. It is possible to mill them to the #6 deck height and then cc them to be matched. I have done it a couple of times. Jerry

ok, thank you Jerry.
