so quick backstory im in the middle of a turbo build and i am replacing the lifters and find i have castech 706's. So i find a set 799 local to me for a good deal. now here is where i dont have a idea on what to do. i have a 06 silverado cc triple 12 cam, nnbs intake, ls9 head gaskets, huron speed turbo kit with a vs racing billet 78/75. i have a semi built 60e with a trailblazer converter, but will be doing a 80e swap in the very near future with a 3k stall. Do i mill the heads to get the compression back up? i do know i will loose some bottom end with the bigger combustion chambers and thicker head gaskets or do i just leave them as is and i wont really notice the difference with the cam, intake and turbo. this is just a street truck not going to the track just looking to have some fun.

thank you

 

I would mill them .030.

 

I agree with 1FastBrick. Mill them get your compression up. I’m running my 408 turbo ext cab with 11.5 comp on 93 pump gas.
