Wow. I was very supprised. I got the car back together and running. It's not done by any means but I got the motor assembled and in the car with the new heads. This is with the same stock manifolds and catted x that was on the car.
I will be putting a set of longtubes on it in a month or two and plan on tuning it with about 12-14 # of boost.
All is the same for right now with the only changes being lower compression and ported heads. I didn't expect to see any gains till I got the headers and added more boost.
I went ahead and made a few passes at Bradenton Saturday and to my supprise I picked up 3mph and dropped almost 3 tenths off of my best time on Nittos. This on a very hot day at noon. I was taking it real easy and shifting it easy at about 6K.
I think this indicates a pretty solid gain for head porting alone. Now I can't wait to get the headers on there and get it tuned.
