Is it only me or are Roller Rockers noisey ?

................U cant use solids on a hyd cam........the ramps are different........a hyd cam needs 20* more duration ......an old racers trick from back in the day was to put hyd lifters on a solid cam gaining 20* dur and the extra lift by eliminating the valve lash that the solid needs............its kinda like offset grinding the crankshaft to gain more stroke.....every little bit helps.......kim.........
