New be needs help with excessive rich running turbo
 

I have a 89 7m gte motor which is running supper rich and stalls when under turbo at 3grand then straightens up mostly when getting to 4500 rpms. I just replaced the head gaskets and bolts due to blown head gasket. Any help would be appreciated.
