Apache heads require a 4.06 minimum bore to clear the intake valve therefore will not work on a 5.7 block. I would mock them up and check it out before trying to run them.
That being said, they are the baddest factory head for the new hemi. Ives heard of flow in the 340cfm range as cast. Indy has a cnc set flowing in the 370's.
Thanks for the "heads-up", I mean honest injun ? But seriously ,is there any word of intake seats coming loose, in the eagle or apache heads ?:dontknow: Thanks, ateam.
