Found some 862 heads for dirt cheap locally and was looking to get pointed in the right direction. I know TEA has a good package, so does AI, not sure if PRC offers it if i send in a core. Anyone on here can share some info?
I am sure that TEA and AI have good cnc programs for the 5.3 heads. I personally do not have experience with them and have heard good things.
I do have experience with PRC 5.3 heads. I have the 2.5 5.3 heads that TSP sells and on the head swap alone I gained 38rwhp and 30rwtq. My numbers are in my sig. My vote goes to PRC especially for the price.
