Car is gonna dyno around 225hp has cp 11.0.1 pistons 82mm & eagle rods, but question is will these valve springs be enough security for my camshafts ? Head is going on gsr block

no

 

big no no

 

Why is that ? Is the spring rate too soft ?

 

no... coil bind

 

Type R springs are still considered to be STOCK springs, Skunk clearly states that if you run those cams you MUST upgrade to aftermarket springs. Coil bind is one big reason, valve float would be another.

 

Have similar set up what did ur car dyno not on the juice ? What type of dyno .... Ill just take the valve springs out of my current b18c when I take my skunk2 tuner 2 cams out supposidly they are skunk2 springs & retainers prob supertech, def dual though dude ran pro1s or pro2s before so must be decent
