Exhaust .253 x 1.5 rocker arm ratio = .3795
Intake .239 x 1.5 = .3585

That is supposedly from Scheid...

The numbers I came up with are 158deg @.050 intake with .238 cam lift.
exhaust is 204deg @.050 with .268 lift. However most 2 valve rockers I have checked are more like 1.6 ratio so that is .380 intake valve and .428 exhaust. Since everyone is also dying to know I am sure lobe seperation is 102deg.
