Mancini/HS 1.6 rocker not giving me the lift expected

Sorry guys; I said in the original post that the Mancini tech told me to call Hughes. That was not correct. He told me to call Harlan Sharp that made them for Mancini. The Harlan Sharp tech was very nice and gave me the specs on the rocker that allowed me to confirm it was a 1.6. He suggested the discrepancy was due to the checking pushrod flexing as I had suspected. Cam is good. Rockers are good. I just need to get my pushrods cut now that I have the best length. No problem with Mancini or Harlan Sharp. I’ve never done anything with Hughes.
