Like it says set of used 706 heads with Yellow Z06 springs for sale. Springs have 1k miles on them. I will do $150 shipped in Texas and add $20 for shipping outside of Texas. Im also open for trades for Nitrous parts or a TBSS or NNBS intake with fuel rail..

SOLD

 

Bumpsky

 

might b interested if they will work with my setup ill let ya know

 

They will fit any 4.8, 5.3, LS1 set up. Great way to bump compression on a LS1.

 

How would they help a 4.8 power wise?

 

True but man i hate those yellows guess if i bought em i would jus have to find a better set of springs.

 

You can always sell the Yellow springs to some one who is running a Z06 cam. Switched99 have them ported n polished n throw a cam in that 4.8 will make a ton of difference.

 

They're the same heads that you have already.

 

bump need these heads gone im open 4 trades...
