Dialing In Jun Camshafts

[unique1]

im trying to find specs to dial in my jun camshafts on my rb26, i want to use a degree wheel and set it up exact but finding these specs is providing to be very difficult and the instructions that come with them are japanese so not much help to me, has anyone got info on jun cams and reccomended specs? Ive even emailed jun countless amounts of times and no reply, the jun auto site seems to contain every bit of info except what i need.

nope... some cams have a larger lift.. meaning it pushes the valves down further... improper shimming and valve/spring combos can lead to valve bending when the piston strikes the valve. Or in extreme cases... breaking.
