I can't tell, but it appears the studs you have are flat style like this:

That allows the rocker body to bottom out onto the stud. If not fixed it will cause serious damage to your valvetrain.
You need tapered studs. You'll notice there is a shoulder. That allows the rocker to sit higher to clear the bottom of the stud:

Get them and recheck your PR length.

True, but adding guideplates to an engine that doesn't require them, and combining them with OE rocker studs, will move the shank of the stud approximately 0.060" closer to the bottom of the rocker arm. This could cause a clearence problem, even if the pushrod length was correct.
