Something I learned from Richard Jemison, the BB "cammaster". Alfa cams wear. Some more quickly than you might imagine. Years ago I had a pair of factory 10.6 race cams in my GTA engine, and after a tune up, it just did not run "right". I discussed this with RJ as I had been through the dual point distributor 2ce, and the Webers and had checked valve clearances. Richard had me tighten up the intake clearances quite a bit, and.... once again it ran "RIGHT"!. Now RJ can probably explain what this happens better than I ever could, so don't ask me. I had some new cams made up for it from WebCam since. These run tighter clearances as new and manufactured, offer quieter running, longer valve adjustment intervals and more low end torque. They are not simply a WebCam copy of the Alfa GTA design.
Check with Richard, Alfar7 on the BB.
This is from my own experience.
