Finally gonna install my blox type b cams in my gsr w/ stock comp. which valve springs should i install the gen 1 or gen 2, I have a set of both. Mostly my daily driver so i won't be reving too much during the week. But it will be getting some track runs hopefully once its tuned.

 

Rocket generally recommends the Gen2's with any cams that are not his. Even though Blox uses good cores.

 

Gen 2's

I believe Gen1's should be saved for the pure race motors

 

use blox spring with blox cams. same if u use toda cams then use toda springs.
cos if something goes wrong the manufacturer is going to ask u what springs u were runing. if u say ????? then they will say our cams arent made to work with those springs. itll save u less headaches.

 

Brilliant post.
