i 've got the mp blu's for my stage 6's , their nos still in the boxes , but the rollers are out of square with the shafts . so i need to get them fixed . but we have some hughes rockers on order . i'm thinking of designing a new shaft setup , to push the shaft away from the valve tip and reducing its dia and going to bushed rockers . i'm talking with my cam designer about this new way to get better rocker ratio so the can does not have to big so radical . i'm a designer and it has no limits i guess . a failure is just a way not to do it , right . lol .
