Great information on this topic. Sorry OP, im not trying to take over your topic. I'm just looking at doing a very similar cam swap. So i just want to make sure im understanding what everyone is recommended. Seems like everyone is suggesting going with a LS2 Chain & LS6 Springs with this cam assembly swap? I will be running my stock converter as well. Also, will be installing "LPP LT Headers" at the same time. Any help would be great guys. Thanks for all the info.
