I did the dual guide conversion following the brewed Motorsports guide pretty simple but i have 1 concern there is 0 clearance between cam and rocker arm. Nissan does not give this spec, i've contacted brewed motorsports waiting for reply, anyone done this can share some info in regards of cam to rocker clearance.

You really should shave each guide shim individually to match the thickness of each flat shim that it's replacing.

That has been done and measured all are within .012mm that's not my issue. I am wondering since the cam is petty much touching the rocker arm with 0 clearance is this normal. Will this cause excessive wear? I'll try to take some pics today to show you what i mean.

I talked to brewed motorsports and they told me nissan recommends .14 to .17mm from cam love to rocker arm pad surface.

So I was given wrong information reason nissan does not give camshaft to rocker arm clearance because there isn't one. The hydraulic lifter removes any slack so the rocker arm rides on the cam at all time.
