KYB shocks?

So my 25+ year old adjustable Koni shocks finally blew on my '72 Swinger- I hopped on Rockauto.com and ordered a set of KYB gas-adjust shocks all around as I've had good luck with them on other cars. Ideally, I was hoping to replicate the smooth/slightly stiff ride of the old Koni's as the KYB's were the only ones listed under the 'Improved handling' tab.

My question is- will these shocks ride too rough? I started seeing reviews from B & C body owners that they did not like the stiff ride from the KYBs. Should I send them back before installing?

Thank you for your help,
