Nice numbers! I finally got mine figured out too. I have a very similar build but I have l92 heads, fast102 setup , similar cam but on a 115lsa. I have it at 10.2-1 compression for when I put the blower on it. Still a blast to drive NA tho

I would get 1 7/8 headers and a better flowing ypipe (keep your catback) with a 25% UD pulley and dyno it on a dynojet and leave it be.... Don't go to crazy bc they you will hate the car

If any exhaust change up. I personally would go with stepped headers 13/4 to 17/8 tjeb look into tsp true duals . The paceatter y pipe known to be not good merge and there is power and torque being held back there. Looks like a strong setup congrats!
