As far as the inconel valves go is that something that would be sufficient for big power. Or should I just go with the bare heads and get custom cams? I also want to go 4.6 not 5.4 beacause of the shorter throw. Do you recommend a 5.4 GT block over a teksid to make 1500 HP or stay with the 4.6.
What are the rods good to on a GT? And how much of it can I keep for big HP.
