I have a Indy headed 440-1 running a 739 lift cam with heavy heavy springs.

Anyone else running a high light setup in the street?

What do you recomend for rockers and push rods??

That's awfuly big for the street. You might want to post this in the race section or call the cam maker and see what they recommend. I hope your valve springs are up to the task as well. I'll bet you'll have to have a custom set made.

With Lift like that , is the cam a roller or a flat tappet ? , one you you don't want to skimp on is the valvetrain , cheap chinese junk is not an option here , unless you want a multi thousand dollar repair bill soon after start up.

With 440-1's you need offset gear to begin with and more importantly what are your spring pressures ?

Its all Indy roller setup.
Springs are huge, not sure pressure yet.

Well you need to find that out but I see something like T+D's or Jesels in your future, break open the piggy bank.
