300: 'read that string. That's kinda where I got the idea nobody likes the E6s. I found sets of E7s locally, today (1 on a motor, 1 in the bed of a truck and 1 on a shelf, dozens in a bone-yard). Found a set of E5s and a set of E8s too. I've been searching eBay and cl all week. $150.00 is the magic # on Ford parts. $150.00 for heads, $150.00 for valve job, etc.
Ultimately, jr. has to pay for half the total cost of the truck. I think we've decided to go back to the E6s. I'm going to see if the guy can weld the crack. If not, E6s it is!
