    .312*1.7 = .530 lift
    .300*1.7 = .510 lift

    umm with 130lb springs you should be ok, IMO. you could do 1.65 rockers,

      it's possible, but will the heads be able to use the extra lift?

      .312 in. lift w/ 1.7 rockers is .5304
      .300 ex. lift w/ 1.7 rockers is .5100

      stock heads flow well up to .5000 lift, normally.

        WickedSix from Crane flowed some stock heads and they did not peak until well after .550" lift, STOCK. They were actually pretty impressive completely stock.

          You guys know that anything over .530 requires the heads to be milled, right?

            You can also use ZZP's special valve stem seals and modified retainers, you can go up to .560 lift without milling.

            I asked Zoomer about this a few days ago and that's what he said.

              My bad all, I did forget to say that i did do head work about two years ago, at that time the guy at the shop said there was no cam for my car at that time. I felt they were give bull....
              now that I got one why not, and if i can put 1.7 rocker to get extra lift and I hope it can be done, I'm going to do that to. I know the best people to ask is all of you guys, cause you guys know what you all are talk about. thats a fact. thanks.

                You do realize that milling the heads will make the valves closer to the piston right? This will in now way make it safer for higher lift.

                I ran .528 lift no problem with 105# springs and i had the valve seal pedastools milled.
