Im buying new rocker arms and was wondering has anyone used the Mancini/Harland 1.6 Non-Bushed Rocker Arms on mild Roller Cam engine (Lunati 60333, 210 seat/ 550 open)? The max RPM is 6800rpm.

I have a new set of PRW Stainless steal that will be soon for sale, 1.6 bronze bushed... They Retail at Mancini for 500 and have life time warrentee.
 
Ok, I bought a new Harland Sharps set in 1.6 for 668.00 Shipped.
 
Okay, you have chosen a good rocker system, but don't install the Harland Sharp rockers right out of the box. They must be prepped just like the PRW or any other rocker arm set. The need to be completely disassembled, inspected for aluminum burrs, dirty threads and nicked adjuster screws and cleaned. In addition inspect the ball ends of the adjuster screw and make sure they are smooth balls. Some Harland adjuster screws have been shipped with burrs on the balls that break off and ruin the ball and pushrod. Make sure they are clean, clean, clean before you install them!
