The heads are being put on now
Jerry, what do you suppose caused the pushrods to bend? You said you hit 7K, RPM by itself doesnt bend pushrods. Then the thread turned to chamber volumes(?)
You bent pushrods because something collided, most likely a valve to piston. Has your LMS disassembled the heads and measured out your valves?
If they havent suggested some further investigation about your bent pushrods I would be very concerned. Take the opportunity to look further..
