Pushrod for hydraulic cam and 273 rocker arms

I just set up a 340 w/273 rockers yesterday. 68-340 block decked about .006 , .053 felpros , j-heads , lunati hydraulic lifters. Perfect overall pushrod measured 7.125. Nothing off the shelf available. Used the aformentioned 7.190 proform pushrods. will work with about a 1/2 turn showing .
