Also, i took off my valve cover to check my upgrades, and i saw that i have some crower valve train. I was wondering if they come on stock or are they upgraded valve train.

Another question is does shortshifter matters? let me know asap please, about to some tune up and upgrade to my car this saturday thanks!
