pushrod length ball to cup

OK

After waiting forever for my parts I finally got everything and turns out my assumptions about length sucked ;-)
After carefuly measuring I realised that I need 8.450-8.500" pushrods. These will be perfect.

Now my question is:
I have 2 piece 9.125" 440 chromoly pushrods set, can I put them apart, cut to what I need and put them together or will I decrease durability of such pushrod?
My questions are wierd cause I wait forever for parts delivered to Poland at reasonable (still crazy) shipping cost and allways try to use what is available in my hand before any purchase.

Thank you guys!
