And can I have an Amazon link please?

Thanks in advance!

@the_red_viper: I think you mean Ghost Rider #12 : Apocalypse Soon Part 1 (World War Hulk - Marvel Comics): Daniel Way, Javier Saltares: Amazon.com: Books

I know there's a fight between the two where GR just goes away in the end because Hulk didn't commit any sin or something. Is it that one? If so is there a graphic novel where it's included?

@the_red_viper: Hmm that sounds like an early encounter, you should ask @theacidskull

Johnny let GR loose, and he rode away because Hulk hadn't shed innocent blood.

The Hulk animated series had an awesome fight between Hulk and Danny, where Hulk was poisoned and GR was trying to keep him Hulk until he burned through the poison.

I think they fought in Hulk: The Animated Series and World War Hulk.

They fought in an issue of the original GR series. Johnny entered a desert race and encountered Hulk during the race, who had been given coordinates there by Mephisto's minion. Hulk was attacking the racers, so Johnny and some other racers circled around him to cut of his breathing, which made him faint.
