Default Need to replace push rods?

Soon to install zz4 camshaft and 1.5 comp cam roller's in 89 with 75,000. Do I need to replace the push rods as well as valve springs etc.
Installation sheet say's if you dont change you will void warranty,its just I have not read here when other's have fitted new rockers they have changed out there push rods as well.
Also What are the oem spec's of the standard pushrod length/dimentions?

So long as your staying SA and not installing "proper " guide plates, no need.
Stock SBC roller pushrods are 7.200

Push rods are pretty inexpensive, even the hardened ones. I can't think of any reason not to replace them while your in there.
