Head shim on Nytro

[4strokesnewbie]

I know some of you guys have installed headshims on the nytro. I'm currently installing an impulse kit and somehow didn't get the headshim part of the instructions. I've been trying for days. Anyway, I have the head ready to go back on and don't have the torque specs for the head or where to put the timing. Do I have to slot the sprockets to get the timing back? I'd appreciate any help as it is holding up the install. Thanks guys

tork to 20 lbs. back off 1/4 turn and retork to 20 lbs. then 180 degrees, make sure you follow the proper sequence, not sure how much the head shim is on the impulse kit so I can,t help on the cam timing.

If you want I will scan my instructions and pm them to you, the headshim on the impulse kit advances the timing 2.26 degrees, I retarded the intake cam back to stock position. I installed my headshim back in November, and I still have all the paperwork, with the timing, torque, and head bolt sequence. There is also a sequence for the camshaft caps, in a criss cross pattern working form inner caps out.
