Mike,Comp has not made their own hyd roller lifters for many years Johnson supplied them,Isky and Clay Smith for many years.They went to Ron Shaver Industries here in So Cal to make the S lifters and subbed Morels if out.Many cam company's buy from Morel.Comps new lifters look like Shaver bodies with in house made replaceable cartridges.Actually made by a Edelbrock company.I dont think any of the major cam companys are knowingly buying China made hyd roller lifters.Tom
