A few things were done differently to my heads but nothing substantial.
The cam timing has not been altered yet as that will take a long time on a dyno to test properly and keep adjusting.
It wasn't a huge improvement on that run, about 15 RWHP based on the times. Initial tune with no tweaking yet, a front wide band O2 sensor had gone out, the ported intakes weren't on yet to let the heads breathe yet and worse traction. The cams compliment the heads well but they were not ready at the time either.
