And the same exhaust *gaskets*?   You really can never reuse them.   I am 
betting on an exhaust leak.   Did you re-torque the header bolts after you put 
the motor in the car and ran it once or twice?   They normally have to be 
re-torqued, or they will loosen up, and once that happens, you will quickly blow out 
the exhaust gasket, and the resultant exhaust leak will manifest itself as 
big pops in the exhaust under trailing throttle.

Been there, done that more than once (in fact I just recently had to change a 
gasket on my Pantera motor because the bolts loosened themselves and it blew 
the gasket out).   Check the intake manifold bolts too--mine loosened up on 
both the Cobra and Pantera....
