can i use these with stock lifters and stock pushrods with a e303 cam?

  • You can use the stock lifters. I would recomend upgrading to roller rockers when putting in a slightly bigger cam. Then once the new rockers are in you must check t he push rod length. To check the push rod length adjust the rockers. Then turn the motor over by hand until the valve spring is fully compressed. You want the tip of the rocker close to the center of the valve tip.

    I didn't notice the advise to mill the stock heads so the inside spring had clearance which resulted in 16 bent pushrods, one broken rocker and a couple broken springs during the motor break in. My own fault but make sure to note the possible need for machine work.

    Nice Springs

    Having my heads ported, a valve job done, and the valve seats refinished. Going to install these springs with 1.6 roller rockers. Will upload photos when completed!
