So I bought these heads from speedmaster and Im lost. I need to know if anyone knows pushrod length using e303 cam? The max lift on these is .550. Plus i was told i need stud mount rockers. I really need some direction.
Trickflow has a how-to write up to find your push rod length. You will need an adjustable push rod, available from Summit or Jegs (I'm guessing, I got mine from Summit...) in order to check.
And if your heads have screw in studs (which I'm sure they do), you will need stud mount rockers. You can get roller rockers if you so desire, but you will also have to install guide plates.
