I use to adjust the valves on my 235 with a box-end wrench and a screw
driver. I had a mild "clifford Research" hydraulic cam and just lowered the
idle speed down some, loosened the lock nut and then backed out the
adjustment screw until I heard that famous sounds and then tightened the
screw until it went away and then a half turn more before locking down the
lock nut. They do make a tool like you describe and I want to say I seen
it in the Comp Cam Catalog www.compcams.com, or Summit Racing Catalog
www.summitracing.com/ . I need to look into purchasing that tool myself.
