alignment at +.030 , have not done a full sweep yet , can´t find my checking springs. I´d like to check the full sweep with some .040 hughes shims under the shafts.

They hit because the rocker geometry is WRONG. It will be wrong with damn near any rocker you use.

The Hughes shims are JUNK. They are, at best, a half assed fix and they can break the saddle.

The best fix is found at b3racingengines.com.

Go read all his tech pages and then call him and get the RIGHT correction kit for YOUR application.

Anything else is not correct.
