New motor with .488 hyd-flat tappet cam. Broke-in and running fine. Puled heads off for correct spring pressure replacement and decided to increase the lift with 1.6 rockers. I Bench-set the 1.6 rockers but the roller tip is a little past the center of the valve tip towards the exhaust side. Can I shim the rocker bar to achieve the correct geometry? I know it may need longer pushrods. No problem there if needed. But the geometry is still not perfect. I can live with the 1.5 set if no other solution. I don't want to change cam bearings and cam and lifters, ect. I would leave it alone if that's the only way to get a higher lift at this point. All answers greatly appreciated.
