My 4.2 head has shoulder bolts any particular reason for shoulder bolts, some have a stem that sticks out the top almost even with the top of the valve cover. I would prefer to you hex head bolts, they LOOK better, any reason not to?Can't find any to buy at Summit or Jegs. Dealer wants $10 each. <img src="/forums/images/graemlins/lol.gif" alt="" /> Re: 4.0 Head Conversion [Re: burtv] #821314 06/26/07 11:47 PM Joined: Oct 2006 Posts: 2,079 Arlington, Texas Brown81CJ5 Body Damage is Cool check out Quadratec They probably have, or can get what you are looking for.

I want to use head bolts not studs. Use the 4.2 push rods or 4.0 push rods on the 4.0 hean conversiom I have read it both ways but what does the real world say?
