Throttle body
I recently changed the heads on my 02 C5, I upgraded to the LS6 heads after one of the stock LS1 heads shot the #2 spark plug out and stripped the head. I'm wondering do I or should I change the throttle body to accompany the new heads, If so does anybody have any suggestions... Also what is the stock LS1 size and if I should change it what size should I go to.. Thanks

Yes worth it, and yes tuning because you will be lean after the swap. I went from an LS6 intake tuned to the FAST92mm and LS2 P&P TB and picked up 15whp. On stock heads too. So you stand to gain allot.
