Thank you for the replies. As far as HP and torque goals are concerned. I am looking at maybe 110HP out of this. Remember it is going into a vehicle with the aerodynamics of a brick and heavy. I kept the K14 because of it's early spooling throughout the rev range and I plan on not allowing it to go above 18PSI. I understand that I can get much more HP and torque with the LR IP but, once again, heavy brick. I am aware of the swirl bump in the intake ports, which assists with atomization of the fuel and air. My plan is to smooth it a bit, but from my understanding, the more it's reduced, the more the fuel just get dumped into the chamber and less efficient atomizaton, more heat, more black smoke. I also understand that the exhaust ports should remain smaller and it seems like that step from the head to the exhaust manifold allows the hot air to move quicker to the exducer, creating quicker spooling response. So with that information, port matching the exhaust ports may not be the ideal scenario. And smoothing out the intake chambers (opening up the bowls), grinding down the valve stems, and opening up the D ports, plus using some grinding paste on the valve seats and valves seems like the best option. What do we think?
