Thought I would give everyone an update. The engine is still torn apart. The new forged pistons that Ford is using in the crate engine are a real pain. The valve releifs are not centered perfectly for an AFR head even though they have 2.02/1.60 releifs. Ended up making deeper releifs in both the intake and exhaust. And let me tell you, forged pistons are really hard to cut releifs into. Practiced on an old engine before going to the crate motor and the non forged pistons are alot easier to notch. Some other issues we ran into are that you have to do research on which rocker arms that are used. I ordered Comp Pro Magnum rockers for stud mount 7/16 and the trunion of the rockers will not clear the valve springs. This is even with the longer studs that AFR said you have to use. So I ordered and tried Probe rockers (did not work) and then TFS rockers and they work. When we got the motor back together and filled it with coolant, we had a leak on the back of the head. Turns out the new Ford Racing Sportsman block has revised water passages so the Felpro 1011-2 head gaskets don't cover the water jacks perfecly. So the engine came back apart. I hope the new gaskets will work. Oh, and when I see "we", I am referring to my buddy who is doing all the work. What a great sport he is! I really owe him won.
