My buddy picked up a similar kit. He got it for his mustang. I guess he isnt going to put it on the car, he is saving up for a supercharger... When is your truck going to be all done?

The heads look beautiful!
Isn't there something to be said for the rougher finish on the intake ports though? Wouldn't a rougher finish cause more turbulence and help keep the fuel in suspension as opposed to on the walls of the intake?

Either way, it still looks pretty! If the flow numbers aren't all that different, then maybe you should just stick it on the coffee table as a conversation piece. However, I doubt it will end there, since hopefully it was a worthwhile expense.

on carb intakes, the fuel had to actually travel through the runners in the manifold and head. the distance from the fuel injector to the intake valve on our fuel injected heads however is only a matter of a few inches (maybe 5 inches or so). at the speed that the air is flowing through that runner and with the better spray pattern that a fuel injector provides compared to a carb, I don't believe that it will be an issue. but it's all just a matter of theory at this point, as I've never actually hung out inside an intake runner for any period of time while the engine was running 
we'll see if it works or not pretty shortly.
later,
