And if the studs holding the exhaust manifolds onto the heads start pulling out (stripping the threads in the heads) you will find it almost impossible to get replacement heads (and costly!). They were specially made for the RV vehicles.
This did happen to our 460 in our class C. Fortunately it was discovered after we traded it on our '89 GV.
Felt really bad for the new owners, as we thought everything was fine. The dealer did cover the replacement and thought we were lucky to get rid of it just in time.
