I've spent the last couple weekends chasing down an internal coolant leak problem on the Bronco (460), and after replacing the intake gaskets and timing cover gaskets I'm 90% sure I solved the problem. However, that 10% of me, and also the part that likes to avoid future problems, feels that it's possible the leak could have come from the head gaskets leaking coolant into the lifter valley. I was thinking about retorqueing the head bolts this weekend to see if the bolts actually require some tightening, or if they don't budge then I'd feel pretty safe that nothing has loosened up over the years. In the 10 years I've had the Bronco I haven't had the heads off once, so I'm just curious what you guys think if I should go to the trouble of retorquing the heads, or if that could possibly cause problems like warpage, or if I'd just be wasting my time because it's been fine for this long. Thanks!
