Default Push rod lenght to use

Hey guys running a set of TF 220's that have been milled to 59cc LS2 heads on LS1 motor. Im running 7.400 push rods at the moment. I think they may be too long and holding the valve open. What ones should i be running with this set up?

There are too many variables in this one to guess at it. I would HIGHLY recommend the $20 pushrod length tool so you can eliminate the guess work. Next time one of your buddies needs to use the tool, do it for him and charge him $20 for telling him the correct length and your tool is paid for!
