Can’t get Harland sharp rockers to fit on head?

I use this chart and it works well for me. Rotate the engine until the intake valve opens and then starts closing on cylinder #1. Once it closes you will be on the compression stroke. Start watching the piston and when it reaches the top you should be at 0* TDC on the balancer on cylinder #1. Adjust the intake valve on #2 cylinder and exhaust on #8 like the chart says. Then just follow the chart from there.
When all adjustments are made, get cylinder #1 back to the compression stroke like said above, then you can drop in the distributor. Look and see where the rotor button is pointing under the cap. It should be pointing at the #1 plug wire post on the distributor cap. If in doubt once that is done, just post here where you are at and we can go from there.
