Can you change the length of a stock pushrod?
If your motor is all stock, the answer is no. Your stock pushrods are designed to be within the acceptable length range even in the worst case tolerance stack-up situation. Changing the height of the cylinder head changes height of the rocker arm relative to the cam, and therefore it needs to be factored into the needed pushrod length.
What kind of engine is a pushrod motor?
Pushrod V8 engines have been the staple of V8 engine production for a very long time, from all manufacturers. (In fact, GM continues to use pushrod motors in all their V8 applications with pretty solid results.)

We remove the lifter blocks and Harley lifters in this procedure to give you a better view. We cut the pushrods and will use adjustable pushrods during reassembly.
How does height of cylinder head affect pushrod length?
Changing the height of the cylinder head changes height of the rocker arm relative to the cam, and therefore it needs to be factored into the needed pushrod length. In particular, it’s very common to “deck” a head to raise compression in a high performance motor.

Where is the pushrod on a modular motor?
Sitting above the camshaft, in their own respective bores, are lifters. Placed on top of each lifter is a pushrod, a cylindrical rod (with ball or tapered ends) that on the bottom end sits on the lifter, and at the top pushes on the rocker arm.
What to do with a bent pushrod motor?
Remove the bent pushrod by pulling it up through the cylinder head by hand and set it aside. Inspect all of the other pushrods for wear or cracking if the motor is equipped with a rocker shaft assembly. If there is severe damage on one cylinder bank it is prudent to inspect the other bank for damage.
