I still have these.....open to offers!

 

how would these do on a 4.8? 112 is coming.........., drop the CR?

 

Its the same head you have on the 4.8L. Put since you have a Radix coming, I would take it and have some bowl work done and that would make a great head for that new supercharger....give you a little more power.

 

Bump for $160 shipped.

 

Do you have valve covers for them?
