So i had my 383 ls with ported 225s but i found put they were oppend to 245. And bc of that my na numers sucked so i am putting a d1sc lowering compression and putting brute speed blower cam. Do u think its to much head and it will hurt my numbers and get a 225 trickflow or stick with the heads

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?

10.1 to 1. Just very concered bc it only made 396 at the week n/a n compression was 10.9 also with a vic jr. I think i was just flowing way tomuch air and it was killing it

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.
