hi, will smith bros 9.215 push rods work with unported factory 906 heads 383ci and lunati .475/494 @ .50 duration is .220 @ .50 hydraulic cam? it seems long to me thanks

Most of the info is insignificant. What's important is "hydraulic cam". Now we need to know if you have stamped or adjustable rockers and if adjustable do they have a cup or ball adjuster. FWIW, unless you've had some significant machining done to the block or heads, a "close to stock" length pushrod should be fine. But IDEALLY you should get a "checker pushrod" and order exactly what you need.

Stock 383 hydraulic pushrod with stock rockers is 8.593
