these are the heads you snipped from me on ls1truck. lol. are they nice. im still interested. but why dont you want them. did you feel any bump in power when you ran them.

 

i never installed them. i'm going with a forged 370 build instead..

just let me know when you're ready.

 

just to let you know paypal frowns on the seller passing the 3% onto the buyer...bump for ya...i'm kinda interested

 

if the buyer doesn't agree with the 3% for paypal fees, then the buyer can pay for shipping.. i'm pretty lenient if the buyer has a concern or problem with my for sale ads.

thanks for the heads up,
let me know.

 

hi , would you ship international ?

and i ve got another question , i m not into this head cam valve thing from v8 engines i ve only driven europe diesel cars before , so do i need anything else to make these work on my stock 5.3 year 2005 ?

i could look into it, but i can't promise you anything.. if the price is right, we can work out a deal. where are you located? pm me if necessary..
