I would have zero issues running that head, espically if you have a cam custom grind to your setup. once you are in boost it isnt going to matter anyway.

How much are you going to lower the compression?

If the VicJr had an elbow-that's what killed your N/A numbers.

No need for a VicJr unless you want to shift it past 7500.

I'm still using a LS6 and a 75mm TB.
