INSTRUCTIONS, on the procedure
Find Top Dead Center
before you can set the ignition timing or install a cam correctly youll need to know how to locate TOP DEAD CENTER on cylinder #1
yeah, it takes a bit of work and a few accurate tools, but you don,t need to do much compared to tearing the engine totally appart to expose the cam, you can meassure lift and duration accurately at a valve retainer or even more accurately with the rockers removed at a push rod tip
a simple dial indicator fixture, on a push rod tip after removing the rockers from the Number 1 cylinder, and a degree wheel on the crank hub,and a piece of graph paper and your time to graph out the lift vs degree of rotation, would give accurate info, that is going to be a whole lot less work and gives you FACTS VS guessing at the answer

any time you change cams youll need to use a matching distributor gear, the cam manufacturer should be able to help tell you what matches, obviously checking clearances helps
and dipping the gear in moly assembly lube before it installed helps
be sure you inspect the distributor gear for excessive wear
especially if you changed from a flat tappet to a roller cam.
if your seeing the timing change a few degrees, back and forth,
slack in a worn, loose timing chain, worn distributor gear or not having the proper shim clearance on the distributor center shaft will provide slop that allows timing to vary several degrees

when purchasing a crank socket try to find one designed to easily accept and lock down a degree wheel
THE COMP SOCKETS ARE FAR MORE DURABLE STEEL

YOU CAN AVOID POTENTIAL CONFUSION & PROBLEMS IF YOU TAKE THE TIME TOO, DEGREE THE CAMSHAFT IN, instead of relying on "dot-to-dot".
btw when checking for TDC its usually best to pull all the plugs it makes spinning the engine by hand FAR easier
Fasten the degree wheel to the crank, with a washer and a crank damper bolt.

WHEN CRANK IS AT TWELVE AND CAM IS AT SIX THEN #6 CYL IS FIRING AFTER YOU LINE UP YOUR MARKS AND INSTALL GEAR THEN ROTATE YOUR CRANK ONE
REVOLUTION AND THEN DROP THE DIST. IN - AT THAT POINT

Take a stiff 1/8-inch TIG welding rod or similar material and sharpen one end to form a pointer, and wrap the other end around your needle nose pliers so that a 360 degree loops formed so a bolt and washer can secure the pointer wire to the block in a convenient bolt hole location.
Attach this pointer so that it rests very close to the damper and the point is at the degree wheel edge to eliminate parallax viewing error.
IF THE HEADS ARE OFF THE BLOCK
Obtain a stout strip of steel about seven inches long, drill three holes, two for head bolts and one centered on piston.
Put a bolt in the center hole to stop piston movement.
OR IF youve got the tool required, ...A deck bridge you can bolt it in place and insert a bolt that prevents the piston from reaching and passing thru top dead center in its rotation,
This strip or the correct tool,is then placed across the center of No. 1 cylinder bore and bolted on each end to secure it to the block.
Caution: Be sure that the strip of steel is rigid enough so that it will not be deflected when the piston contacts the center bolt stop.
Incidentally, the positive stop should be adjusted so as to stop the rotation the crankshaft in normal running direction (clockwise) until the piston crown lightly strikes this stop.
Now, radially turn and lock the degree wheel to the crankshaft at 40 degrees before T.D.C. at the pointer.
Rotate the crankshaft backwards to the positive stop.
If the degree wheel reads 40 degrees from T.D.C. you have hit Top Dead Center exactly, and the zero mark between the two 40 degree readings is absolute T.D.C..
However, if your readings were unbalanced, you will have to split the difference (your errors in degrees) by moving the degree wheel radially on the crankshaft.
Then, try again until you get exactly the same degree readings against the positive stop on either side of T.D.C.
NOTE: The lower the positive stop is located below T.D.C., the greater the degree readings will be.
The results will always be accurate.
T.D.C. always lies equidistant between the two positive stop readings.

IF THE HEADS ARE ON THE BLOCK
youll screw a piston stop into a spark plug thread hole and accomplish the same thing
