I need the part number for the LT4 valve springs i did a search but didn't find any. Also i'm getting the LT4 RR to go with them from a friend that works at a chevy dealer are there any other parts that i need for this instalation and if u ahave any part #'s that would be great Thanks Jason

 

12551483, 4 come in a pack so get 4 packs obviously. It'll be like 2 or 3 dollars cheaper if you get 4 packs rather than getting them all in the kit.

 

p/n is 12495494 for the kit of 16
