We have reached an agreement with Dynamic Cylinder Heads LLC, a company in South Dakota, on the sale of our Vortec, Vortec Bow Tie and Dart SS cylinder head programs, machinery and processes. See video on our home page. Here is Nick German’s contact information: Dynamic Cylinder Head LLC, 310 N. Linda Ave. Unit #10, Tea, SD 57064. 605-214-2248

All inquires for new heads and work to your heads should be directed to Nick at Dynamic Cylinder Head.  Nick purchased our 5 axis Centroid machine that does the porting work and several other pieced of our equipment. He will have access to our customer records and has the exact valve seat cutters we used for years.
