I took mine to Key Puckett at Fishin World in Dallas Tx.. He is an expert w these motors and holds a lot of world records. They shaved the heads on mine, changed out the exhaust tuner and drilled the exhaust. Putting on and injection head is about $1500 and in my opinion is not worth the $$$ for 1-2 mph more the motors just don't flow enough air. Felt like an extra 50hp really made a big difference. I think the comp. went from 130psi to 145psi, that way they still can run wfo and not get hot. If I recall I spent about $1500.oo
