Insanely impressive for a stock head! Already very smooth and wide open, barely even a need for any porting, if anything I'd say it only "needs" a tiny bit of smoothing/cleanup.
We got the Mil.Spec IM/TB set along with MAP phenolic gasket installed tonight. Took us about 5 hours start to finish which included a pizza/Throwback Dew break and time to R&R the stock undertray. The manifold itself wasn't really a problem nor were the support brackets...it was all the damn wiring harness clips and the TB coolant line clamps which were at a very precarious angle. The coolant lines to the TB could easily be bypassed with a 180* bent hose to loop to/from the thermostat housing. We decided to skip this for now since we didn't have a hose like that, didn't want to kink a factory line, and were excited to just get the car back together! I had no idea just how much material Aby @ Mil.Spec actually removed from the IM runners until I had it side-by-side with the stocker! I reset the ECU and overall the car seems to be idling just fine; a tad high right after startup but the ECU quickly corrects and brings it down (this may just be because I reset the ECU, I'll find out tomorrow once I actually drive it a bit).
My tune is scheduled for noon tomorrow so later on in the afternoon I'll be reporting back with some final numbers
