I have a set of 5.3 Ls1 cylinder heads for sale. Heads are in great shape they have been shaved .020 has a competition 3 angle valve job cut and has some mild port and polish work done. Heads can be supplied w/ stock 5.3 valve springs, retainers,and locks. I'm asking $400.00 shipped.

 

happen to have any pics?

 

no sorry, maby lator all I have is dyno results w/ the heads on the motor

 

how much power do they add......and they are direct bolt up to a stock motor.
