AMS has discontinued cnc ported head
As i was shopping for head work, I contacted AMS for pricing, and unfortunately they no longer offer this service. I thought I'd share with the community.

Unfortunately we have currently stopped production on the CNC program on the Evo 8 heads due to us seeing a casting error in the heads from the factory. There is a bubble in the casting by the guides that we have found can be opened up in the CNC process and allows coolant to flow past the guilds. It can't be seen and there is no way to test for this besides bolting it on the car and starting the engine. We have not seen this on all the Evo 8 heads, just on a couple that have come through here in the past year and unfortunately it is just to much of a liability for us to offer them. We don't want to offer an product to a customer that has a chance for error so at this time we are discontinuing production until a solid solution can be found.
