any1 have this combo? does it require flycutting?any input would be great, thinking of getting heads!

 

I don't imagine it would require flycutting since the LS6 heads have stock valves and the G5X3 works fine on stock heads. However, TSP has a new cam out designed for the LS6 heads they have. I believe they can bump up the compression on them as well. In a 6.0L goat I believe the H/C numbers were 450+hp and 400+tq.

 

I am planning on going with the same setup. I will flycut since the x3 makes for shitty dynamic compression and I want to bump it up. I think I will mill 15 thousandths if possible. need to check some clearences.

 

.015"? Thats just a scratch.

 

I eventually want a 11.75 compression so i'm guessing I need to mill a good bit.
