Yes my custom headers on my Daytona made it a breeze. On my heads up car they are fab headers but the class rules dictate it has to be a stock firewall and stock mounts for the front suspension. I knew running nitrous pulling plus was going to be a commonplace thing. Even though I never started the engine I addressed that issue and found a set of through sockets and ratchet at Harbor Freight. I wish I had this tool forty years ago. Lol
