Ok I have a 2000 Civic SI, I am currently rebuilding it due to a thrown rod... upon taking it to the machine shop (Local) to get a valve job, have it cleaned and valve stem seals replaced. Also to have the bottom shaved to make sure its not warped... Called them today and they told me that I should have a full set of double springs, but I only have it on one side... he didn't specify whether it was intake or exhuast side. I just wanna know if I should have the whole head that way or just one side and if so which side... thank you for any help you can give me.

 

on a stock b16 head you should only have dual valve springs on the intake side, the exhaust side only has single valve springs

 

yes correct, intakle side= dual valve springs, but i would reccoment if you ever wanna put bigger cams in it that you get dual valve springs for intake and exhaust, i mean you already have it at the shop
