Lakewood is the only one who can recertify lakewood bellhousings via quicktime/ holley. The address is: 6674 189th street Albia, Iowa 52531. You can call Russ there and ask him for a work order number. 641-932-5050. I believe lakewood was upset that other manufacturers/companies were recertifying their bellhousings and they were losing revenue so they took the issue to the SFI foundation and changed who can recertify their products.
