Need a little help with pushrod length please

[ian8950]

Hello everyone, I'm having some trouble getting the correct pushrod length and could use a little advice. my current setup is as follows:

Edelbrock 7122 Cam Lift .496/.520
Edelbrock Performer Intake
Edelbrock E-Street heads part number 5023
Comp Cams Roller Rockers 1.6 ratio
Fel-pro head gaskets Part Number 1011 (I believe these are the standard thickness)
Engine Bored .30 over but this shouldn't matter - including for completeness' sake

I obviously need to purchase new hardened pushrods for this, but I'm having a hard time finding what size. I ordered and received a length checker/tester rod but the nuts on it will not fit through the pre installed guideplates on the heads so I cannot use it. Except for ordering several pushrods of varying lengths to test does anyone have this setup or have any other ways for me to measure my pushrod length? I have a set of stock hardened pushrods that I ordered before realizing that I might need a different length - these show 6.80 as a length.

Here's a couple pictures, i coated the nub with graphite, attached the rocker and turned the engine by hand two rotations. Line is the contact point. Does this look good? First time doing this

Thank you for the reply! One last question; after securing them all down there is a little side to side play in the rocker, is this ok and normal? Note: no up and down at all, just a little side wiggle.
