Lunati Roller Rockers

I have Lunati Roller Rockers that Are 1.8 X 3/8" Studs. I also have 918 springs with stock 317 heads and 7.4 hardened push rods. I am about to go tune the car and want to make sure I have a good sound engine. With the cam on my sig. are these good??

Stud mounted rockers are a step down from stockers.

That part number is a 1.8 adjustable rocker. The stock rockers are 1.7 non-adjustable. Your .595/.588 lift cam would be .630/.622 with 1.8 rockers - too much for 918 springs. Before you choose a rocker you need to clarify your requirements.
