I live in Redlands but I work M-F in Corona so I cover quite a bit of distance most days. Phelan isn't too far at all. However the last two sets of heads I have bought have both been condemned by the machine shop for cracks. The second set I got from a member here who promptly dropped out of sight.
You sure these are solid? What happened to the motor?
I will PM you my phone number and let's see if we can work something out.
