I know this must be a silly question but are the prices for the heads listed on tea and absolute speed for both heads I am sorry if you all laugh but, on the sdpc the ls6 are listed for a single head. Just made me wonder.

No, all aftermarket companies list their heads as sets.

GM dealers like SDPC will list heads as singles in their online catalog.
