I have decided to pull the motor and plan on having the eddy rpm heads and intake ported. Any suggestions are welcome on lifter and cam combos for the street for my 511. I will probably step up to the 2" step headers from TTI. Thanks! Andrew
Your spec sheet showed seat pressure, but what did it have over the nose? That looks like not enough spring load. The needles didn't seize. They flat spotted the pin and then the roller didn't roll.
