Thanks James, all info is appreciated.
As a side note, what do you guys think would be the next turbo ( currently using TA 49 with home ported heads) to take advantage of these heads. They are stock unported.
I was told these are the 8 bolt for 109 blocks , yet in the pictures there are an additional three holes, a total of 11. Are these heads made to fit both stock and stage blocks?
