flywheel ?

Opinions ?

While changing out the tranny in my drag car for a freshen and new Frank M tranny brake, I noticed that it has a stock type flywheel. I ordered a new SFI Scat zero balance and was wondering if I should get it checked for a zero balance ? Also if I decided to change balancers should I also get that checked ? Its a old school offset ground cast crank w/alum rods for a 500"

Thanks Mark

I had my CSR flex plate check and the ATI balancer check when I had my machine work done they both was dead on. He told me that he has not found any out of spec of these brand but if I have to change them for some reason to have them check to make sure.
