the heads are new and i have stud type rockers. i checked the valve adjustment and it is ok. i run fuel pressure at 39 to 40 psi. i have 190 gph pump. and i have 19 lb injectors. i am beginning to think it is the cam. i have changed everything but the air intake sensor but it is ok. it didnt start this until i did the mods to it. but i put stock intake back on it and it still does it.
