I has a gsr turbo'd motor.. and I was thinking about Blox B cams, but I have the skunk 2 pro series valve springs and titanium retainers. The guy that is going to tune my car, said that I would be better off sticking with the gsr cams...

My setup is:
GSR Block with ls crank, ls eagle rods, and ls forged pistons 85mm..
Ramhorn manifold
t3/t4oe ar.63

I was wanting the most out of this setup.. But i don't see a reason why my friend would say not to get the cams..

And also is the skunk 2 pro series valvetrain too harsh for stock gsr cams or eithier blox b's or even skunk 2 tuner 2's cams..

Thanks in advance.
