Well, I guess you can think of this as a good time to upgrade to a 2g head then (Some will say its a downgrade, but I have seen a few cars lose power when going 2g>1g head and gain power when going 1g>2g head. 95tsi on here made 360hp on his 2.0 with a 2g head, switched to a 1g head and a stroker, and lost 13whp. Different setup and all, I know, but he still lost horsepower. I think it's because the 2g head just flows better (not as much in raw airflow, but a smoother air path than a 1g head)

Shane will probably tell you the same thing.
