I think you will be okay. Fwiw, unless you already have the parts, FT Pontiac cam cores are hard to find and some of them are of questionable quality. There are not any quality SFT lifters currently available. IMO you might want to consider sticking with your current lifters (assuming you feel they are without issue) , reprofile or replace your cam with gentler lobes and soften up your valve springs some.
