340, hydrolic lifter 273 rocker solid pushrod no oil hole

TSB says grind the rocker for larger springs. seems to be some meat there. Mechanical rockers all the way, worth the 'hassle'. Use the solid pushrods. They dont channel any oil, thats supplied from the lifter galley directly into the lifters oil hole in the banded area.

When I ground down the 273 rockers for clearance (1.47 to 1.50 springs) on our
stock eliminator cars after perhaps 20 passes the would crack around the oil
hole and if not caught in time = actually separate from the shaft.
I did run 150 to 165 on the seats of the springs = You might have less issues
with stock spring pressure!
