With the block on an engine stand, install the crank and one rod/piston in the #1 hole. Install the camshaft with the timing set you intend to use. Install a degree wheel on the crank and bolt a wire pointer to the front of the block. Purchase a cam checker of this type....
...and degree the cam per instructions....
Once you have established the 0.050" tappet lift specs, match the static compression ratio to the cam. This is just bass-ackwards of the way this should be done. Normally, you would establish the static compression ratio you want to run and then match a camshaft to the SCR to achieve the desired results. The tools to degree the cam will cost more than a new camshaft on which you know the timing to begin with.
Read through this list of don'ts before you begin with a flat tappet cam...
