I used the valley plate for the 400 block. Its a nice quality part but there is a good gap between the plate and the head that needs to be filled with RTV. I think this part is only for the MW/270 head, the standard port/240 uses a valley pan.
I used Andy's valley plate and bat wing gasket system and it works quite well with my TF 240's.
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
