... The exhaust rocker works a little harder then the intake... Didn't see a performance advantage for the dollar spent with this combination... We are running very low Spring pressures on this motor.... Spring pressures that would make most people cringe
With spintron testing, its crazy what they are getting away with on spring pressure this year. I have a big block that see's 8-9000rpm all day. Has T&D steel rockers and never have had an issue with them.... see the large offset BBC rockers break all the time.. FWIW I run 525#'s closed and 1485 # open
