First of where in cali are you located? I know of a couple modified gps here including myself running a VS cam setup. Depending on the cam you got with will depend on springs and chain. i stayed with a single new of course and running #90 springs. personally if you run the 105s go with a double to be on the safe side and not have to change it out as often as a single. Had a guy running xp and 105's and a single chain he almost trashed his engine. his transmission went out took apart the block to look at the chain and the dampner was literally about to come off. he had 10k on that setup. better to be safe imo. if i were you sell the manifolds and dp combo and go headers.Originally Posted by getsumbaby
