go to the hardware and buy a very lite(weak) setup springs for intake and ex you will need to take off your intake and ex springs .then use the set up springs .all the time checking that you are not pushing the plunger down in the lifter . the wire size on the spring s i have for checking hyd lifter cams is about 030 thick or less just needs to hold the valve up no more....... 510 should go with out long slots but you can check from the under side of rocker slot to rocker stud with a paper clip bent out so you can slid it up there. it should have alot of room 510 is not bad put many together with 500 with stock rockers . check any ways its good thing to do
