oke i got a b16a2 head rebuilt with the stock duel intake side valve springs and inners and i got a set of spair intake inner valve springs if u use them in the exhaust side will the motor be able to rev safely to 8700-9000 rpm or should i get a set or after market valve springs also runing stock retainers

 

bump

 

Using what cams? How many miles are on the valves?

 

runing b16b cams and the head was rebuilt and had a valve job and the springs had less then 80tho km on them

 

Id be willing to bet CTR cams wont make power to 9k.
