273 rocker info please

Be sure to use the banana groove shafts.

You will need to grind clearance to use them with stock Edelbrock valve springs. Other aftermarket heads may need that also. Or you can be smarter than I was and switch to beehive springs.

In my case Mike @ b3 recommended .030 clearance between the keeper and the rocker. It is easy to check that with a piece of welding wire.
