    I’m curious being the SP3 is single plane if the fuel distribution is way more even ( I’m assuming so) that my o2 sensor that reads off the left header collector is going to be the same or damn near close to the right side?

    Should be. I have two bungs and they read real close to the same....

    Mark, is your intake port matched? Sure seems as if something is holding engine back. What did them heads flow?

    Yes intake was portmatched to my iron heads which were gasket matched years ago, so the intake port isn’t really that skinny like stock. Have no idea what the heads flow, when I had a ( Chevy ) machine shop install the larger TA valves they also did the bowl work and gasket match, so who knows how much they flow:rolleyes:

    What’s your valve clearance like with the hi compression pistons? You got valve reliefs?
