You do not have to pull the heads to remove the valley pan with Indy heads. Slice the RTV between the head and the tray with a knife. Then run the knife under the tray at the china wall. Tap the tray rearward with a block of wood, the RTV will break loose since its been cut. The tray can ow be tipped out of the valley. Done it more than few times.
Nothing like a bunch of crumbled RTV bits to clean out of the valley !!! While you have that pan out, throw it in the trash and install one with the removable center.
