well i am in the process of building a LQ4/L92. i currently have a 2000 ls1 and i have head studs already, but i read that the blocks changed after 2004, and my LQ4 block is a 05 block. my problem is: can i use my head studs from my 00 ls1 on a 05 block? or do i need to order the ones for the 04 and up LS1/ls6...???

thanks
Charlie

 

you need the new ones. i had to get new ones when i went from an 01 ls1 to an 05 lq4.

 

alright, thank you!

 

sell your old ones, i did.
