Pulling apart my gsr head for a port job and when i removed the valve spring.. It had dual valve springs on the intake side and on the exhaust side it didn't. Is this normal for a gsr engine. Or did some one put these in. I never pulled off a gsr head before.. The engine is all stock when i purchased it.

 

yes, the intake only come with dual spring. UNless ITR with is dual spring on both.
