I was VERY happy to have that timing cover on the SBC - it saved me from having to screw around with a cover that only allows pre-adjustment/setup of the backlash - not after it has actually ran a bit.

Hi Dale, do yourself a great favor and get away from using cam buttons at all, all-in-all they are a "headache" to setup (time-consuming) and just more "moving" parts in the unit (this is assuming you use the roller buttons like we use to)!
P.S.
If you have time here's a method we actually devised over here to eliminate the buttons in the early SBC's, we set them up like the later OEM roller units with the stepped-nose cams and the thrust plates. We've actually sold dozens of the installation kits so far, containing ALL the necessary tooling/components to set up the early blocks with the stepped-nose cams, mostly to other machine shops. No more "adjusting/measuring/shimming", put the cam in, bolt on the thrust plate, throw on the timing chain, and you've got your .003"/.004" end play! If you have time follow this link here, the entire story is over on the Chevelle site! Makes no difference anymore which timing cover you use!! We've built "dozens" already with our method.
