Rocker arm side play

Thanks for he info Joe
Those Harlans IIRC are $700 without the shafts or hold downs, don't think I can afford those. The rest of my valve train is comp so maybe I should go with theirs for any warranty issues that may arise from the rest of the comp pieces.
Just pray the ole 18 will hold up long enough to get all the parts I need to finish the 360.
