Jim's notes show 1.800 installed height and 1.100 coil bind. The Lunati cam will have 6.15/6.21 lift with the 1.65 rockers and this would give .079 clearence to coil bind.. The book says you want .1000 clearance if you really spin the engine. If I get the Butler ra iv roller cam I will have .142/.105 clearance. So what do you think?
