Re: Engine is back

They touched everything up and knew I was running a hydraulic cam so didn't see enough discrepancy to affect what I was wanting to do.

Re: setting valve spring heights

Check the micrometer with your dial caliper to ensure it's reading correctly. Lots of complaints about those mics reading off for people due to the calibrated distance being inside the cup and not to the rim of the cup. If your retainer rides on the rim of the cup will need to know how deep the cup ...
