Default Looking to do a Rocker arm upgrade....Which would be best?

I have a 408 ci. with a set of Stage 2 P&P L92s. The cam im running is 232/236-595/602-115+4 with stock Rocker arms. Im looking to upgrade to a 1.8 1.85 RR to increase lift to get better use of the Flow on my heads. The springs are good up to .650 lift.

I used this cam, because my car is my DD and I wanted driveablity. And I knew that I wanted RR later.

So which is best?

If you go with 1.8 or 1.85 ratio arms, that will push the list well into the 0.635"+ range. Have sure the heads will flow in that range. Some P&P L92 heads are design to flow max around 0.600" lift. Also check the springs to make sure they are good for that lift. Also remember that high ratio arms will also increase the duration amount a bit too.

I know they will flow up to .700 lift. the flow sheet I have for my heads puts me around 348cfm @ .650 lift. And I know it could use alittle more duration. But im also waitting for the LSXR Fast intake to come out so I can do them both at the same time.
