I'm switching from a 1997 non-PI head to a 2002 PI head and the bolts that go trough the timing cover to mate up to the heads are the wrong size.The right size of thread for the new bolts are 10mm 1.50 pitch,does anybody know if ford sells these bolts or do they come as a kit and what part numbers go with these bolts.Does anybody know if these bolts can be purchased somewhere else than ford.I have everything tore down and was hoping to get the motor back together this weekend.Please send any info you might have.Thanks a bunch
